Polyesthesia

Polyesthesia or polyaisthesia is a neurophysiological condition in which, in response to receptor irritation, several sensory nerve impulses occur. Some experiments show that the number of such “aberrant” sensors reaches four or more. These experiments were carried out by Swiss neuroanatomist Donald Looney on the study of adhesive ganglion cells in sea anemones. Looney believed that the presence of several sensors arises due to genetic reasons: as a rule, if a cell produces one process, this means that this type of sensor corresponds to a certain type of neuron, which has one neurite, so there are usually many such cells. On the other hand, one can think differently: several aberrations represent a variant of the norm, which makes the adhesive cells more adaptive and labile.

**Polyesthesia** is a unique phenomenon for many people. Some people have never experienced it, and some people are lucky to be born with this unusual gift. To understand it in more detail, let's look at the basics and try to understand how this perceptual process works.

**Polyesteresia** is a special sensation that allows a person to feel touch on all the skin of the body. This occurs due to a special chemical reaction in the human body. Nerve fibers located under the skin are used as reagents. Their sensitive endings are located on the surface and are able to perceive the slightest changes in temperature and pressure. Touching an object to the skin causes corresponding impulses. At the same time, the fibers responsible for the sense of touch are stimulated. As a result, a person feels heat, pressure or cold.
