Neurobiologists from Institute of Technology of California turned information from a brain of monkeys into the faces of people. Thanks to a modern tomographic technique of measurement of activity of neural cages by the scientist it was succeeded to recreate data, necessary for a research, in accuracy. It is possible to examine work in the scientific publication Cell in more detail.
Face recognition, as well as some other images, happens in the lower part of temporal area of a brain where the arriving information is coded in neural cages. Still quite recently scientists did not understand how it is possible to decipher these data because of what carrying out any experiments connected with recognition of objects did not make any sense.
Now specialists of Institute of Technology of California conducted own research within which it was succeeded to progress in understanding of process of neural enciphering considerably.
On the first phase of a research, 16 various images of persons were shown to two primacies, including 80 other objects . Then, by means of functional MRT, neurobiologists calculated what neurons are responsible for definition of human physiognomies.
In different regions of the lower temporal share experts allocated separate groups of nervous cages:
On the second phase of a research neural elements which helped to distinguish the person with individual traits and characteristics were found.
Actually it means that primacies could understand where there is a girl and where the man.
For this purpose scientists prepared several portrait images simulated by means of the computer graphics including the database of concrete lines of a physiognomy.
The result of an experiment allowed to find existence of interaction between three allocated areas — ML, AM and MF. As it appeared, of Anterior medial is responsible for the end of processing of persons . In the same area the group of neural cages which showed special activity proceeding from various features of portraits was found.
At a final stage of an experiment more than two thousand additional faces with further reproduction of the obtained information proceeding from activity of cages in a certain area of a brain were shown. Data on functioning of separate neurons were translated into mathematical language that gave the chance to define activity of cages with features of human physiognomies.
Following the results of additional selection, the persons shown earlier practically differed in nothing from the revealed information interpretation.
