The effect of early locomotor training (running in a squirrel cage from an age of 1 month for 3-6 months) on evoked potentials of the rat visual cortex during ontogeny was investigated. It was established that intensified proprioceptive afferentation causes a statistically significant reduction of both the latent periods and the recovery cycles of excitability of primary responses of the visual cortex to paired light flashes, whereupon the increase in functional activity is more pronounced with respect to the indices of the excitability recovery cycle than with respect to the latent periods or primary responses. The indicated functional changes correlate with the quantitative increase in the density of dendritic spines on neurons of the visual cortex of both layer V, which are primarily the integrative-triggering apparatus of the cortex, and of the complex of layers II + III, which are primarily associative with respect to their functional significance.
研究了早期运动训练（从1月龄开始在松鼠笼中跑步3至6个月）对大鼠个体发育过程中视觉皮层诱发电位的影响。结果表明，增强的本体感觉传入会导致视觉皮层对成对闪光的初级反应的潜伏期和兴奋性恢复周期在统计学上显著缩短，因此，相对于潜伏期或初级反应，功能活动的增加在兴奋性恢复周期指标方面更为明显。上述功能变化与V层视觉皮层神经元以及II + III层复合体树突棘密度的定量增加相关，V层主要是皮层的整合触发装置，II + III层复合体在功能意义上主要是联合性的。
