¿WHY TICKLES MAKES US LAUGH?
 The brain of rats explains why

-Summary

Rats have tickles in the belly and feet, when you touch that zone they emit vocalisations high-pitched, so high-pitched that they are ultrasounds that are the same as laughs of humans.
This observations they did do in the university of Humboldt where for investigate the bases of laugh in neurology.
In the university they didn't only look the behavior, they did also investigated the group of neurons in the cortex "somatosensorial" that are used in this behaviors .
The results show that like humans anxiety inhibits tickles.This proofs that the cortex "somatosensorial" not only responds to stimulus manually.
This explains the pleasure of pats in animals or touch in humans.
Maybe the sensation of tickle is a trick of the brain for like this the game and interaction with others is gratifying.
