How the Brain Perceives the Body

How the brain perceives the body and how the body looks are two completely different things. For example, the brain enlarges the mouth and hands.

The brain perceives the body differently than what the mirror image looks like. If you look at how the cerebral cortex is connected to the different body parts, it becomes clear. The left hemisphere (red) performs movements while the right side (blue) receives sensory impressions. It turns out that a large part of the cerebral cortex is connected to the mouth. The hands also take up a lot of space, but the upper body does not seem to be nearly as important.

Experiments during brain surgery

This has been achieved through experiments with patients who are operated on in the brain. The surgeries can be long and patients need to be awake. Therefore, they find it nice to have a little variation in the meantime. When the researchers stimulated the cerebral cortex with weak electrical current, patients experienced it in different parts of the body. Afterwards, the researchers were able to draw a map showing where on the brain’s surface different parts of the body feel.

Homonculus is a picture of how the brain perceives the body

Homonculus shows how the brain perceives the body

If you draw how the brain perceives the human body, it looks much like Homonculus above. In other words, it’s distorted. But the picture is not entirely correct. For example, the figure should have even bigger jaws and also gape more. The inside of the mouth is huge in the brain. It allows it to act as the body’s laboratory. If we want to investigate something really carefully, we’ll put it in our mouths and chew on it. This means that large parts of the brain work together to analyze the object.

Discover your mouthfeel with JAWPEER

The interaction of different senses in the mouth is called mouthfeel. With the mouthfeel, we can determine what is edible and what is not. Sensations such as heat, dryness, and tingling are recorded by chemical means. The mouth sensation arises from a combination of different nerves in the mouth and on the tongue. That’s why we experience things better that we put in our mouths. Unfortunately, the mouthfeel is too rarely used. If you want to stimulate it then there is now a good product: JAWPEER. Since we have different tastes and tastes, it can contain different large and different hard CHEW PEER. The idea is that you should be able to find your own favorite and then subscribe to it if you want.
