Study to reveal pruritus feels that really knows " Infect "
A lot of people have such experiences, see someone else scratch and itch, a certain place can't help itching too on oneself. A latest research shows, people's pruritus feel can really be infected, perhaps this is a human a kind of brain activity mechanism that forms in evolution. American researchers ask some volunteers to participate in the relevant experiment, the volunteer watches a section of anyone scratching the video that scratch itching or not respectively. The result reveals, watch someone scratches and itches the volunteer of the video, presents the behavior of scratching itching more, its frequency is about twice of other people's. Researchers say, these phenomena prove pruritus feel will really be infected, may because there is a kind of special mechanism in people's brain in this, this kind of mechanism only receives others and scratches the signal that itch even just talk about and itch, will convert it to thinking the signal that oneself itches. Once studied and revealed that there is this kind of situation in animals such as monkeys,etc. too in the past, researchers think, this may be because the common ancestor of monkey and the mankind lives in the collective with close relation, if member a certain appear louse wait for parasite and scratch, itch at body, other member begin, scratch, itch too see, this contributes to controlling the spread of the parasite, if things go on like this form the infection mechanism that pruritus feels gradually.
