Abstract

At comparison of the data obtained in psychophysical and electrophysiological studies, disturbances were revealed of neurophysiological mechanisms of visual perception in children with the diseases of retinocortical tract. For compensation of the disturbances and development of perception a method is suggested of specific activation of neuronal formations based on their fundamental property--plasticity. The method consists in using rhythmical repeated stimulation of eyes with images which widely vary by the brightness, contrast, colour, form, orientation and spatial position in the visual field. Experimental verification of the method was conducted by a special program of correction studies with children having weak and residual sight. After 2-3 years of studies a significant increase was observed of probability of correct recognition of images by one parameter or combination of two parameters, increase of perception volume and improvement of its other properties. It is supposed that activation of sensory information processes lowers the level of deprivation and mobilizes reserve mechanisms of compensation in the projection and associative areas of the cerebral cortex.

摘要

在比较心理物理学和电生理学研究中获得的数据时,发现患有视网膜皮质束疾病的儿童视觉感知的神经生理机制存在紊乱。为了补偿这些紊乱并促进感知发展,基于神经元形成的基本特性——可塑性,提出了一种特异性激活神经元形成的方法。该方法包括使用具有广泛不同亮度、对比度、颜色、形状、方向和视野中空间位置的图像对眼睛进行节律性重复刺激。通过对视力弱和有残余视力儿童的特殊矫正研究程序对该方法进行了实验验证。经过2至3年的研究,观察到通过一个参数或两个参数组合正确识别图像的概率显著增加,感知量增加,其其他特性得到改善。据推测,感觉信息过程的激活降低了剥夺水平,并调动了大脑皮质投射和联合区域的补偿储备机制。
