The daynamics of functional-structural characteristics of residual neurons was studied in the degenerated lateral geniculate body (LGB) in various periods of time (4-12 months) after neuronal isolation of the neocortex under which all geniculo-cortical connections were cut. Background and evoked spike activity in the degenerated geniculate body were studied as well as the number of persisting cells and their diameters. Neuronal receptive fields were found to undergo destruction along with the prolongation of postoperative period. A gradual diminution in the quantity of light sensitive cells was revealed. Background spike activity was predominantly of a simple type. Progressing decrease in cell number and cell diameters was observed under the morphological examination. Special features inherent in geniculate interneuronal relations are discussed.
在新皮层神经元分离后不同时间段（4 - 12个月），研究了退化的外侧膝状体（LGB）中残留神经元功能 - 结构特征的动态变化，在此过程中所有膝状体 - 皮层连接均被切断。研究了退化膝状体中的背景和诱发尖峰活动，以及存活细胞的数量及其直径。发现随着术后时间的延长，神经元感受野会遭到破坏。揭示了光敏感细胞数量逐渐减少的现象。背景尖峰活动主要为简单类型。形态学检查发现细胞数量和细胞直径不断减少。讨论了膝状体中间神经元关系所固有的特殊特征。
