Biologists found the cells responsible for the sense of touch

One of the recent studies have revealed a whole group of cells responsible for the sense of touch. Opening called Merkel cell, writes the journal Nature. Located throughout the body, they define the sense of touch and tactile feeling.

The higher the density in a specific area of the body, the stronger the degree of its sensitivity. For example, on the fingers of these cells is several times larger than other parts of the body.

In addition to the cells, scientists have studied neural connections by which the signal reaches the brain and gives feedback. This forms a pleasant and unpleasant sensations.

Merkel's cells give a person a feeling of pleasure from touching, kissing. Now it became clear why walk by the hand and kissing is one of the degrees of trust between two people.
