Candies in a box, you can call man's sixth sense.

Thanks to this sense, we can determine how many elements of the same kind are in a place at a given time.

It is known that there are five basic senses: sight, hearing, touch, smell and taste and each of them has its own topographic map in the brain, that is, a map that shows where the neurons that form them are located. Now scientists have found that such a map exists for the perception of quantity.

Sense of quantity different from symbolic numbers. The latter we use to represent quantities or other quantities. When we perceive quantity, we visually process the characteristics of the image.

To better understand what controls our sense of quantity, scientists conducted a study on eight participants. They asked them to look at cards with different numbers of dots. During this experiment, the researchers analyzed the response of neurons using functional magnetic resonance imaging.

As it turned out, there is an anatomical the "quantity sense" center, which is located in the back of the parietal cortex.

Scientists say that this part of the brain, which is responsible for the perception of quantity, works like a sixth sense.

"When we see a small number of elements, we don't need to count them. We immediately know how many there are," explained study author Ben Harvey of the University of Utrecht in the Netherlands.

human feelings

We know the basic five human senses. However, some scientists believe that we have them, at least nine, and some claim that there are more than 21 of them.

By feeling in this case is meant a system of a group of sensory cells that respond to certain physical phenomena and correspond to a certain area of ​​the brain.

Here are the basic and other lesser known human senses:

Five human senses

Vision- in fact, it can be divided into two senses, depending on the type of receptors: color vision (cones), and brightness (rods).

Taste- some believe that taste can be divided into five senses, depending on the taste buds (sweet, salty, sour, bitter and umami). Umami determines the taste of the amino acid glutamate, which is present in meat and is used as a flavoring agent.

Touch also considered a separate feeling from pressure, temperature, pain and even itching.

Hearing- the ability to perceive the vibrations of the environment, such as air and water, which are in contact with the eardrums.

Smell- the ability to detect odor.

Other human senses

Thermoception- the ability to feel hot and cold.

proprioception is a sense by which we determine where our body parts are located in relation to other parts of the body. This feeling is tested by the police when they want to know how sober a driver is by conducting a test "close your eyes and touch your nose with your hand." We also use proprioception when we want to scratch our heel without even looking at where it is.

Feeling of tension Tension receptors are located in the muscles and allow the brain to monitor muscle tension.

Nociception- the feeling of pain has a unique sensory system, and is not an overload of other senses.

Sense of balance helps us maintain balance and sense body movements as we accelerate and change direction. With the loss of this feeling, a person ceases to distinguish up from down, and moves with difficulty without outside help.

Thirst- allows our body to monitor the replenishment of fluid loss.

Hunger This system tells us when we need to eat.

magnetoception is the ability to detect magnetic fields in order to know the direction of movement. This sense is well developed in birds and insignificantly in humans.

sense of time- there is a lot of controversy about what helps a person to determine time. However, studies have shown that we have a very precise sense of time, especially in our youth.

Even in ancient times, people began to notice that a person tends to perceive the information surrounding him differently. This perception is carried out with the help of the sense organs. Thanks to them, a person gets a complete picture of his environment. The question arises: how many sense organs does a person have.

It is believed to be five. They tend to respond to a variety of external factors. These are the sense organs, which will be discussed in the article.

Characteristic

The main sense organs are:

1. Eyes - with their help everything that a person sees (vision) is accepted;
2. Nose - recognizes pleasant and unpleasant odors (smell);
3. Ears - perceive vibrations of sounds and take part in the regulation of balance (hearing);
4. Tongue - is responsible for all kinds of taste sensations (taste);
5. Skin - here sensitive nerve endings allow you to feel touch (touch).

These 5 sense organs are conventionally divided into two groups:

1. Tactile - they can be called simple in their nature of impact. It is touch and taste. Because the initial stage of information processing by the brain is carried out with direct contact;
2. Remote - this is sight, hearing, smell. Everything represented by these feelings, the individual perceives remotely. Certain parts of the brain are responsible for creating images and evaluating what they see. At the same time, intricate analytical chains are built.

Let's take a look at each.

Vision

The eyes are considered the most beautiful of the sense organs, they are also called the “mirror of the soul”. They provide 90% of the information about everything around and what is happening. Even in the womb of the fetus, the eyes are formed from two small pimples that emerge from the brain.

In the form of nerve signals, the presented image is sent to the brain center, where they are decoded, assessed and understood.

With the help of six separate muscles, the eye can rotate in different directions and be directed to any object. I would like to note that visual acuity or the ability of the lens and cornea to refraction of light depends on refraction. When rays of light enter the eye, they begin to focus on the retina, forming an image.

Excitation in the retina of nerve cells leads to the formation of various kinds of impulses, depending on the color and brightness of the light, which are examined and analyzed by the brain. Then everything is folded into human-readable pictures and views.

Hearing

Human ears are made up of three sections:

1. outdoor;
2. Medium;
3. internal.

They act not only as an auditory organ, but also establish the balance and position of the body.

The outer ear starts from the auricle. She conscientiously protects the ear canal from injury. Hairs and special glands are seen in the ear canal. The latter secrete sulfur in order to protect the ear canal from the smallest specks.

The functions of the auricle do not end there. It not only protects the ear from negative influences, but also works as a catching device - with its help, sound vibrations are sent straight to the eardrum.

The middle ear contains the hammer, anvil, and stirrup. With their help, the tympanic membrane communicates with the inner ear, where the cochlea is comfortably located - an important auditory organ. The vibration of the eardrum transforms into nerve impulses that are sent to the brain and read as sound there.

Smell

The air cavities of the skull are closely connected with the nasal passages. Smells are sensed by olfactory nerves, much like hairs, which are located in the upper part of the nasal cavity. With the next breath of air, they delay and examine the incoming molecules. Capture and perfectly determine the smells hovering in the air. Further, they quickly and clearly transmit the received information to the olfactory bulbs, which are associated with the brain center.

Those who like to drag on a cigarette are likely to have an impaired sense of smell. And with allergic or colds, it can change for the worse until the body recovers completely. Irreversible loss of smell occurs when a nerve is damaged (for example, with a trauma to the skull) or when the part of the brain that is responsible for recognizing odors is pathological.

Taste

With a detailed examination, we can safely say that the main taste buds are the taste pimples. They are located in large numbers on the surface of the tongue in protruding soft papillae. There are four main taste sensations:

1. Sweet;
2. Sour;
3. Salty;
4. Bitter.

Taste buds that determine each of the above sensations are located on specific parts of the tongue:

1. On the back - bitter;
2. On the sides - sour;
3. On the front - salty;
4. The end is sweet.

It is noticed that taste and smell are interconnected - this helps to capture different aromas. A poorly developed olfactory organ or loss of its functions impairs the sense of taste.

Touch

By touch is meant all the sensations of the skin. They are sent from receptive and specific receptors of nerve endings along the nerves themselves, which are immersed at different distances and depths, into the thickness of the skin.

Free nerve endings respond to touch, a slight increase in temperature, and cold. Some respond to vibration and stretch (closed nerve endings), while others instantly respond to pressure. Thermoreceptors respond to the sensation of heat and cold and rush to send a signal to a certain part of the brain to regulate body temperature without fail.

In a disease that destroys nerve fibers, the peripheral nerve system, or the brain, the sense of touch is more likely to be impaired. Local damage to skin receptors can lead to such unpleasant consequences.

Well-developed sense organs given to us from birth are wonderful helpers in human life. They promote good orientation and adaptation to the environment. Each feeling is unique in its own way and necessary for a full and vibrant life.

Somehow I thought about how to make my memory work better and not have to turn to specialists to remember the most important moments in life.

And I realized that it is necessary to use all channels of perception - vision, hearing, smell, taste, sensations, feelings - then the events will leave a vivid trace in the memory.

Moreover, such memories are treasures for the soul.

The perception of events with all the senses allows you to live life to the fullest, and it is they who turn the simple moments of life into jewels.

In this article, I would like to suggest ways how to develop 5 senses, improve the perception of information and saturate life with new emotions.

I propose to start every day under the motto: I open this wonderful world around!

You need to pay attention and do a little research.

Developing the 5 Senses: 5 Simple and Effective Exercises

1. Development of visual perception: please the eyes

Remember the expression "the eye rejoices"? This is usually said when it's nice to look at something.

It is important to please yourself and expand your visual perception. These may not be new things, but when you begin to consciously pay attention to things - their volume, color, texture, unusualness and uniqueness - this turns on the reaction in the brain

“yeah, how many different things I see” - “seeing is wonderful!”

Ask yourself: what pleases my eyes? What do I enjoy looking at?

It can also be a beautiful sunset when the sun glows crimson.

And how the river flows, bypassing the rapids.

And the movement of ears of wheat in the field.

In addition, to develop visual perception, notice the details of the world around you:

• what is the name of the seller in the store,
• how many columns are at the building you pass by to work,
• what pattern is laid out tiles in the store.

The question is different: how to return the joy and spring of life?

Let's think, if the center of sensory perception is our heart, then the antennas that saturate it are our fingers, skin, ears, eyes, nose, tongue.

This means that the more we please ourselves, allow us to see and hear the beautiful, discover the whole range of tastes and smells for ourselves, the more we feel this world, we feel happy.

Why pay attention to your feelings?

Feelings are what make up the experience of the soul and the richness of our lives.

Feelings are directly related to memory. Feelings are the instrument of the soul. What stays with us from life to life.

They influence us so much that it is sometimes difficult to remember childhood for those who have a lot of pain and experiences, memory blocks such memories, works as a fuse.

The good news: the sensory perception of life can be returned.

Remember what you loved to do as a child, and what brought a lot of joy, fun and enthusiasm?

Immerse yourself in childhood memories and look at the world in a new way with childish spontaneity and the excitement of a researcher.

I would like to finally quote one thinker:

Whoever can fill every moment with deep content, infinitely prolongs his life.

P.S. I am sure you will find practical application of this information.

I would be grateful if you share the article with your friends.

Write what feeling you will develop today.

Human sense organs: the main organs, what they are responsible for, how they are connected with the brain. Hygiene rules.

Thanks to the presence of sense organs, we can easily adapt to the world around us. What is given from birth and has been present with us all our lives is of little value, and if suddenly, due to some kind of accident, we lose one or more feelings, we lose a piece of ourselves. Unfortunately, we are not always told from childhood about how important this is, but if you are reading this article, it means that you, like us, have decided to take care of the most important thing in the world - your body!

Let's take a moment to reflect on our feelings:

• Close your eyes and imagine how people live who do not have such a natural gift;
• Imagine not being able to smell the food, the scent of the flowers, and the delicious scents of your favorite family members;
• Think about it if you could no longer taste your favorite dish or drink;
• Imagine that you immerse your hand in water, it begins to blister, but you do not understand why.

And this is just a small list of what restrictions people experience, for whom some sense organs do not work well or do not work at all.

What are the human sense organs?

Human sense organs are the very organs with the help of which a person interacts with the outside world. With the help of the senses, a person can be aware of what awaits him at one time or another when in contact with the outside world, to know it and enjoy life.

How many main sense organs does a person have and how many sense organs are there in total?

Currently, scientists have approved six human senses, but there is constant debate that a person has many more feelings and this is just a concise concept.

The list of human senses includes:

• Ears (thanks to the ears we hear sounds as well as vibrations);
• Eyes (thanks to the eyes we see);
• Tongue (thanks to this organ, we feel the taste and temperature of everything we absorb);
• Nose (the nose helps us hear smells and aromas);
• Integuments (they provide tactile sensations, touch, a sense of pain and temperature of the surrounding world);
• The vestibular apparatus (thanks to this sense organ, we are aware of our place in space, maintain balance and feel weight, position).

5 main sense organs - taste, sight, hearing, touch, smell: their main functions and meaning

In this section, I would like to pay attention to each of the sense organs separately and highlight their significance for human life.

Eyes . With the help of vision, we receive on average about 90% of the information. The pupils with which we see are laid in the embryo and continue to develop until birth, directly connected with the brain.

Vision, or rather visual analysis, consists of several functions:

• eyeballs;
• optic nerves;
• Subcortical centers;
• Higher visual centers in the occipital zones.

Can you imagine how long a signal travels in one instant so that we can see and process information in real time without delay? How quickly the eyeballs, having recognized the signal, transmit it to the brain, and the brain instantly analyzes and gives out a reaction from what it sees.

In addition, eyeballs are an ideal and unique optical device of its kind. Thanks to this, we can see at various distances, and we are also able to see both the whole picture as a whole (for example, a room) and the smallest detail (for example, a scratch on furniture).

The principle of operation of the eyes is very simple and at the same time very complex: light, passing through the cornea of ​​the eye, is refracted and refracted passes through the lens, where it is refracted again and tends to the vitreous body, where it converges into focus on the retina of the eye. It sounds complicated, but you need to know this in order to understand that visual acuity directly depends on the cornea and lens, or rather, their ability to refract light perfectly.

But that's not all! The eyes, thanks to the muscles located in them, are able to move in different directions, which significantly increases the speed of vision, and also relieves stress from the spine.

organs of taste . This organ is responsible for taste buds, thanks to which a person can evaluate the food he eats. This protects a person from eating spoiled foods, allows you to enjoy new and well-known tastes, and also informs the brain of the most acceptable tastes, and therefore, subsequently, the brain signals what kind of food it wants to eat.

There is a misconception that the tongue is responsible for taste, but for some reason they forget to tell that special nipples and bulbs are located not only on the tongue, but also on the palate, epiglottis, and also on the upper part of the esophagus.

An interesting fact: the tongue is divided into several zones that best define one or another taste. But even if the zone is not responsible for this taste, this does not mean that it will not feel it, just not so bright. Example: the lateral arches of the tongue most clearly feel bitter, but this does not mean that the rest of the tongue, palate and larynx will not feel pepper.

It is worth noting that the organs of taste are closely interconnected with the organs of charm. With colds and viral diseases, taste habits can change significantly, and what brought pleasure can cause persistent disgust. After recovery, the situation will stabilize and return to its previous state.

Ears . It is believed that the most difficult to adapt in the world to people who have difficulty with vision and hearing. Indeed, in our fast-paced world it is quite difficult to live without acute hearing, and therefore it is important to carefully take care of what nature has given us.

The ear consists of three interconnected parts: outer, inner and middle. The outside is the familiar shell, which is as individual to everyone as fingerprints. It is responsible for the localization of sound, and also clearly identifies the source of the sound.

In the external passage, which runs from the outer ear to the internal organ, there are sebaceous glands that produce earwax. It is she who, constantly going out, prevents clogging of the inner ear. It is followed by the tympanic membrane, which reacts to sound vibrations. Next comes the tympanic cavity, the base of the middle ear. In this cavity, the hammer of the stirrup and the anvil are connected into a single whole. After them is the cochlea and semicircular canals, which are responsible for balance.

So, auditory waves are caught by the outer ear, move to the tympanic membrane, from it to the three auditory ossicles and further to the cochlea, irritation goes from the cochlea to the auditory nerve and the brain perceives what is heard.

sense organs . Most do not even realize what an important role this function of the body plays. How important it is for us to understand that we are in contact with hot or cold, with smooth, rough, soft or hard. It is tactile sensations that bring endorphins (hormones of joy) when in contact with a loved one. Touching a favorite thing, an animal and even the outside world can tell us no less than sight! Please note that children who have not yet accumulated enough life experience touch everything and it is through touch that they study the world and gain that very experience.

But it is worth paying attention to the fact that the skin (they act as organs of touch) exclusively “catch” signals and transmit them to the brain, and the brain, having already analyzed, reports what our fingers felt.

Nose or olfactory organs . In the nasal passages, a small part is occupied by olfactory cells. In shape, the cells resemble many tiny hairs, and as they move, they capture the subtleties of all kinds of aromas and smells. As in the case of touch, olfactory cells catch scents and transmit a signal to the brain, which is already processing the information. Signals are transmitted in this way: the olfactory cells capture the aroma and transmit it through the olfactory threads and bulbs to the centers of the brain. The sense of smell can be temporarily dulled by viral respiratory diseases and recover within a few days after recovery. Otherwise, the help of doctors is needed.

Language - what is the sense organ?

The tongue, together with the larynx, palate and other parts of the oral cavity, belong to the organs of taste. We discussed the organs of taste in more detail in the section above.

What sense organs do humans lack?

Many people have a question, what kind of sense organs do humans lack? For science fiction writers, this is just fertile ground for creating superheroes or villains. We have identified the most popular sense organs that a person does not have, but if they were, a person would live an order of magnitude more comfortable.

• The ability to pick up ultrasounds is a unique gift of bats;
• Clear vision in the dark - the possibilities of cats and not only are amazing!
• Electroreceptors with which stingrays and sharks are gifted;
• The lateral line of the fish is an ideal sensitivity in space, which contributes to both survival and hunting;
• Thermolocators that snakes are gifted with.

This is just a small list of the possibilities of the world around us that nature did not endow us with or we lost them in the process of evolution.

The sense organs and the brain, the nervous system: how are they interconnected?

Each sense organ is directly connected by nerve endings to the brain and continuously sends signals. The brain, in turn, analyzes the signals and produces ready-made information. It is worth noting that the signal of only one sense organ is extremely rarely transmitted to the brain and most often in a complex way. So, for example, a child enters the kitchen and sees food (vision), hears the mother’s voice “Sit down to eat”, feels the aroma of food, sits down at the table and comes into contact with cutlery (a signal that food will now come), and by the time the mother put a plate on the table, the child most likely knows what the dish will taste like.

How do the sense organs help a person navigate the world?

Have you seen a newborn kitten, how he pokes in different directions, not yet understanding how to navigate in space. So a person without sense organs would move in space without understanding where he is and how to get to the right place, what needs to be done in order not to get into trouble.

For example, a sense of balance helps a person to understand where the earth is and where the sky is even in a room without a single window. Also, a person is clearly oriented thanks to this feeling in space, moving in the desired direction without injury.

The organs of hearing help to hear not only conversations with the family, but also the sound of a moving vehicle, a running animal, etc. After analyzing this sound, a person can correctly orient himself even if he does not yet see this object.

Vision in modern life is one of the key senses, because our society is created in such a way that we receive 99% of information visually. According to statistics, people with visual impairments are the most severely limited in the modern world.

Thanks to touch and charm, a person not only experiences the most vivid and pleasant emotions, but can also protect himself from the dangers of our world. For example, repulsive odors signal to us that food is no longer suitable for consumption before it hits the tongue. The smell of smoke, burning often saves people from fires and allows you to quickly extinguish or leave the premises at the stage of ignition.

Hygiene rules for the main sense organs

In order for the sense organs to serve us faithfully for many years, we must respond to them with care and regular care. Below we give the basic rules of hygiene for the organs responsible for the senses.

• The organ of touch: all our skin needs daily cleaning (shower or bath), moisturizing and nourishing if necessary. Particular attention should be paid to the palms and feet, since it is on their integuments that the maximum number of receptors that transmit the most important information to the brain is located;
• Olfactory organ: as necessary, it is required to rinse and clean the nasal cavities from pollution and substances released by the body. In case of illness, treat according to the doctor's recommendations;
• Organs of taste: the oral cavity needs daily cleaning of the teeth, if necessary, cleaning with dental floss, as well as rinsing the mouth in the morning and evening, and also after each meal;
• Hearing organs: if there are no problems in the ears, then the outer ear should be cleaned after washing with cotton swabs or special buds. In other cases, as necessary, it is necessary to clean the sulfur, but only at the entrance to the ear, deeper, as well as ear plugs, only the ENT doctor should clean;
• Eyes: together with the skin, the eyes must be washed in the morning and evening, if wearing contact lenses, clean them according to the instructions. As tearing, burning or other discomfort in the eyes occurs, it is recommended to immediately consult a doctor.

Video: What controls our senses: human anatomy?

Ecology of cognition: The 5 senses that a person has are 5 methods of perception: hearing, sight, taste, smell and touch. For each of them we have a separate organ or system

The 5 senses that a person has are 5 methods of perception: hearing, sight, taste, smell and touch. For each of them we have a separate organ or system. As part of his treatise “On the Soul”, Aristotle singled out 5 human senses, adding to them a “general sense”, which does not have a special bodily organ. Using this concept, the philosopher described the organizing role of the soul in sensory experience, the actions of which make it possible to evaluate not only the qualities, but also the essence of objects, despite the fact that the ear, for example, hears sounds, but does not see color, etc.

From classical philosophy, the concept of 5 senses came to the European medieval consciousness. The British Museum holds Fuller's silver brooch, made in the 9th century, representing modes of perception. In the center is the Sight, which was considered the most important of all the senses. Around it are: Taste, which holds its hand in the mouth, Smell, depicted between two tall plants, Touch, rubbing hands, and Hearing, with a palm near the ear. And yet, only from the 13th century did the 5 senses begin to be depicted and described in Europe quite clearly. They are quite often mentioned in medieval Christian texts: commentaries on the Bible, sermons and other teaching material - as a rule, in the context of reasoning about morality and vices.

Fuller brooch © wikipedia

Within the framework of literature, the presence in a person of “5 external senses”, or “5 minds” (five wits), is recognized already at the turn of the 16th and 17th centuries. They are discussed, for example, in sonnet 141 by William Shakespeare (translated by A. Finkel):

No, not with my eyes I love you -

All your flaws are visible to the eyes.

Rejected by sight, loving,

Your heart beats incessantly.

And they don't want to hear invitations

To the voluptuous feast of your soul

No taste, no touch, no sight.

But all five senses and the mind are at the same time

They cannot save the heart from bondage.

My freedom is a shadow, and I have long

A mute vassal of your haughty will.

Just one thought consoles me:

You may be my sin, but you are my judge.

“5 senses were singled out in ancient Greece by anatomists and physicians, so this concept, in fact, has always been presented in a scientific framework,” says Sergey Vasilyev, head of the Department of Physical Anthropology of the IEA RAS. “I don’t know anything about the attempts of academic science to change the existing list and add other feelings to it.”

Nevertheless, today it is widely believed that four more should be added to the traditional list of five senses: thermoception (the feeling of heat and cold that the skin provides), equibrioception (the sense of balance, determined by the work of the fluid cavities in the inner ear), nociception (the perception of pain by the skin , joints and organs of the body) and proprioception (awareness of the body and where its parts are located, which provide specific actions of the brain).

“The perception of heat, pain, body awareness and balance are related to the sense of touch and its organs,” Vasiliev explains. “One out of five.”

What would change if a person had 3 senses instead of 5?

There are five senses in the human body: sight, hearing, taste, touch and smell. How much will the picture of the world change if 2 feelings are removed from the chain? What will happen if we deprive the entire population of the world of taste buds? What would happen to civilization if people were born blind? A psychologist, defectologist and art critic shared their vision of life on the planet in extreme conditions.

Irina Salykova, art historian

A person perceives 80-90% of information through vision. Depriving a person of such an important sense organ, I think, we would get a completely different picture of the world, and subsequently a different history of mankind. In this regard, there would be no such thing as visual art. It may have been replaced by tactile or olfactory arts.

If there is no vision, but there is an aesthetic need, then hearing would play the main role in this. Obviously, it would have been developed much more powerfully than it is now. Mankind would do much better in finding new ways to develop sounds that are pleasing to the ear, trying to use every object that came to hand for this purpose. Perception would be enhanced by smells. You can also add dance to this, but there would be no dancers: everyone would dance. How would blind people feel dancing without human bodies touching each other? The art of body movement would be born, the obligatory condition of which would be the participation of all "spectators".

It is difficult to imagine what would happen if people lost two important organs of perception at once: sight and hearing. Would these beings be human at all? The deaf, the blind, the dumb... It seems to me that their only need would have been painting, even without sight, but not in the classic "oil on canvas" version. For example, paints or substances alternative to them would have familiar smells that surround people in everyday life and carry a certain semantic charge. These paints would be applied to canvases in a certain order, combined with each other. And a person who acts as a "watcher" would guess through the sense of smell what he wanted or what exactly the artist depicted. I immediately have an idea of ​​​​still lifes in my head. Perhaps, in this case, still life and landscape painting would be high in the hierarchy of pictorial genres.

Tatiana Siurdaki, psychologist

The information received by the human brain from the senses forms the perception of the surrounding world and oneself. What happens if we remove the sense of taste and smell?

Let's take the common cold as an example... Sometimes people lose their sense of taste and smell during the course of an illness. What changes in this case? We experience discomfort. It is unusual for us, we have lost what has always been by definition. A person eats soup or drinks tea, but feels nothing. He goes to the store and wants to buy a perfume for himself, but he does not feel any difference between the eau de toilette options. He doesn't feel anything at all.

Tatiana Siurdaki, psychologist

If the sense of smell would not exist initially, then a person would be able to adapt to this. When people lose some ability, they quickly find a replacement for it and compensate for it in a different way. Blind people begin to read with the help of their tactile sensations, they read with their hands using receptors located on the skin of their fingers. People who cannot speak use their eyesight. People without arms begin to do everything with their feet: draw, write, they can even change the wheel of a bicycle.

What can happen to food? If people did not feel the taste and smell of food, then they would begin to feel the difference between dishes in other ways. Food could be perceived as colorful, cold or hot, crunchy, giving interesting tactile sensations.

With the loss of smell, the focus would shift to visual, tactile and auditory receptors. There would be no perfume and toilet water at all, but even in this case, people would pay attention to the beauty of the packaging, bottle, box, cap of the product. There would be something new that could use the remaining receptors

Maria Vorobieva, defectologist:

If you are asked to draw a person, what will he be like? Probably most of us will draw a creature with a head, arms and legs. There will be eyes on the head, fingers on the hands and feet. This is exactly the appearance of modern man. This is the norm, the standard. All human life is built for such people.

And what happens when a society appears not like everyone else? Blind, deaf? The answer is simple: they are taught by special methods to live and feel like everyone else. What for? It's just that ordinary people are so used to it. The minority must live according to the laws of the majority! And hardly anyone thought that both the blind and the deaf can live in their own dimension, in their own coordinate system.

"A CHILD BORN BLIND DOES NOT SUSPECT THAT HE IS BLIND UNTIL SOMEONE TELLS HIM." STEVEN KING

And if for a moment imagine that everything in the world has changed? Everyone has become deaf or blind... Will human society change? It will be arranged with a new majority in mind. The criterion for evaluating a person will change: those who do not have or do not have any sensory analyzer will become ordinary, and those who see and hear will be declared people with disabilities. Will the relationship in the system "an ordinary person - a person with disabilities" change? I think no. The presence or absence of sight or hearing does not affect the ability to "be human". published
