[October 29 AFP] — a snake gives fear to those who see why — about this question that could not obtain a clear answer but has so far been made into a mystery, The paper published at the U.S. science academy bulletin (Proceedings of the National Academy of Sciences, PNAS) on the 28th supposes that the special cell which emits warning immediately is in a brain, if a snake is seen.
According to the research team which ? U.S. University of California, Davis (University of California, Davis) Professor Lynn イスベル (Lynne Isbell) (anthropology) commanded A certain specific nerve cell presupposes that it reacts to the image of a snake “alternatively”, and it is said that the stronger reaction was shown compared with the face, the hand, and the nerve cell of the same kind reacted to other images called a geometrical pattern.
In ? experiment, two young apes by which the micro electrode was embedded into a portion called the thalamus pillow which manages the momentary processing to the nudge and intimidation image by the vision within a brain were used.
The various colors and forms which are copied out on a computer screen were shown as two animals.
In this, the form with the face and hand of the ape to threaten and also a star, a simple quadrangle, etc., etc. were included besides the image of the snake of several “different attitudes.”
The brain of the ape which looked at the image of the snake showed the reaction of fear immediately as a result of ? experiment.
Moreover, it was so early that it did not become as compared with the reaction shown to the face, the hand, and the form.
Within the brain of the ape which looked at ? image, about 100 nerve cells showed the reaction.
40% of them showed the greatest reaction to the snake, and about 29% had the strong reaction to a face.
? paper became what newly supports an idea that it evolved so that the primates might have sharp vision, in order to correspond to the threat of the snake in the living environment of a jungle etc.
