Abstract

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.

摘要

干涉测量结果表明,动物从出生起就缺乏视觉冲动,这不仅会导致大脑皮层视觉区域的神经元中蛋白质物质发生变化,还会使运动区域的神经元中蛋白质物质发生变化。然而,与视觉区域出现缺陷类型的变化(蛋白质含量降低、神经元尺寸减小)不同,在运动区域观察到的变化属于补偿性变化(蛋白质含量增加、神经元增大)。本文讨论了视觉剥夺作为外部因素对神经元可塑性特性和功能补偿的影响。
