[An interferometric study of the reaction of neurons in the motor area of the cerebral cortex to early visual deprivation].

Interferometrically is was shown that the absence of visual impulsation from the very birth of the animal caused alterations in protein substances not only in the neurons of visual area of the brain cortex but also in those of the motory one. However, unlike the visual area with the alteration of the deficience type (lowered protein contents, reduced dimensions of neurons), the alterations observed in the motory area are of the compensation order (increased protein contents, enlarged neurons). The influence of visual deprivation as an exterior factor on the plastical properties of neurons and the compensation of function is discussed.
