German researchers found those areas of the brain that are active during decothane. The study involved 30 young people of both sexes, who tickled the heels of each other, while they were scanning MRI. After this they were conducted another experiment, during which they had to laugh without any reason, while MRI scanning is continued also during this time, measuring the blood flow to different areas of the brain.
The scan results showed that during simple laughter and laughter from the tickling intensified those parts of the brain responsible for emotional voice responses and facial mimicry. In addition, has become an active area of the brain responsible for laughter from humorous situations.
But there were also differences. When the volunteers laughed just like that, it became active, the so-called pleasure center in the brain. When they tickled, this brain area did not respond. However, the laughter from tickling touched responsible for the pain area of the brain. It turns out that this kind of laughter is a kind of protective reaction of an organism. Laughter from tickling affects the hypothalamus, which is involved in regulating various functions of a person. For example, there are centers that control human behavior, as well as his emotions.
