Studies have been made on changes in the number of neurones per volume unit of the tissue of hyperstriatum tissue in chick embryos from the 18th day of incubation to the 3rd day after hatching. Significant interhemispheric asymmetry in migration rate and cell death was revealed in the dorsal hyperstriatum from the 19th day of embryogenesis, which may be due to asymmetry in the intensity of visual afferentation which depends on the stationary position of the embryo in the egg. In the activity of neuronal populations within the dorsal hyperstriatum at a stage which immediately precedes mass death of cells (up to 40%), a structure of impulse volley was found which is characterised by the onset of impulse discharges following each other in a form of short series. Sometimes it is possible to reveal correlation between the duration of dominating interdischarge intervals and the extremes in the recovery of excitability of neuronal pools, which indirectly indicates putative reverberative origin of impulse cyclic phenomenon.
对鸡胚从孵化第18天到孵化后第3天，纹状体组织每单位体积内神经元数量的变化进行了研究。从胚胎发育第19天起，在背侧纹状体中发现迁移率和细胞死亡存在显著的半球间不对称，这可能是由于视觉传入强度的不对称，而视觉传入强度取决于胚胎在蛋中的静止位置。在细胞大量死亡（高达40%）前的阶段，背侧纹状体内神经元群体的活动中，发现了一种冲动群结构，其特征是以短序列形式相继出现冲动发放。有时可以揭示主导的放电间隔持续时间与神经元池兴奋性恢复的极值之间的相关性，这间接表明了冲动循环现象的假定回响起源。
