Scientists have revealed left-handedness’ gene
Experts from Oxford University as a result of a long research have managed to reveal a gene which is responsible for left-handedness.
Scientists have found out, that gene LRRTM1 plays a key role in distribution of functions of various parts of a brain.
It is known that the brain is asymmetric. At right-handed persons the left hemisphere controls speech and knowledge of languages, and right – is responsible for emotions. And lefthanders have everything vice versa. And experts assume that gene LRRTM1 is the reason to that.
Besides these functions the revealed gene, according to the experts, can increase probability of schizophrenia development.
So scientists, headed by doctor Clyde Franks from the Center of human genetics of the Oxford University, plan to study influence of this gene on the further development of a brain. According to the statistics, about 10% of the Earth population are lefthanders.
At the same time Franks has noted that lefthanders should not worry about schizophrenia. “There is a set of the factors increasing probability of schizophrenia development, and the majority of lefthanders have never had such problems”, - explained he has.
