Experts explained the mechanism of tickling from a scientific point of view, and answered the most interesting questions on the topic. We know that many people are afraid of brushes. There are several versions of why this is so. According to one, thus appears protective mechanism of the body or in other words — unconditional reflex. Its essence lies in the fact that tickling can detect insects on the body. In addition, there is a possibility that the tickling had become apparent during the development of the Central nervous system.

In addition, the researchers found that during tickling in the human brain reacts just two sites: responsible for the pleasant sensations and evoking protective reflex function. Therefore, some laugh while being tickled, although sometimes it causes discomfort and even severe pain.

It is believed that the sensitivity to tickling is, even in newborns. However, to respond to it babies begin only closer to six months. The reason is that the human brain in early life, yet does not bind the tickling sensation from the influence of the surrounding world. This is evident later in the process of socialization. It is noted that over time, the sensitivity to tickling is markedly reduced.

But people also feel the tickling apes. However, the reaction from them is slightly different, but it has common traits with a laugh. Other animals like the tickling lab rats who are even willing to perform special tasks in order to them once again tickled.

Also, scientists have found that mentally healthy people cannot tickle yourself because the cerebellum of the brain, which precisely defines the position of the limbs. If anyone tries to tickle yourself, it is usually the cerebellum does not respond, because their own hands are not pose a real threat. However, can patients with schizophrenia or significant damage to the cerebellum, according to the publication “Popular mechanics”.
