[Human brain reflexes: from stimulus to recognition and from decision to action].

The paper presents a survey of the data, obtained in laboratories, directed by the author, on the problem of the brain bases of psychics. Phenomena of perception, thinking and taking decision about behavioural response correspond to the afferent, central and efferent parts of the reflex arch. Psychic function arises on the basis of complex organization and integration of the processes in the brain. It is shown that sensation is based on the synthesis in the cortical projection area of the information on physical and signal properties of the stimulus. By means of the method developed in the laboratory, of mapping of intracortical interaction the participation is studied of different cortical zones in the process of mental creation of visual image. The process of taking decision is studied by a new method: "reaction choice potential" recorded in the case of decision, about the character of reaction to signal controlled by consciousness.
