Morphometric analysis of synapses in the medial parts of the ventral and accessorium hyperstriatum in the right and left hemispheres in chicks has been performed after rhythmic optic stimulation from the 18th day of incubation, flickering stimulation at the 11-12th hour after hatching, as well as in chicks reared under normal illumination and those kept in darkness within the first two days after hatching. Numeric density of synapses, mean dimensions of postsynaptic thickenings, the number of synaptic vesicles per active zone in presynapses and mean length of the whole axodendritic contact were determined in ultrathin sections. The data obtained indicate that early visual experience significantly affects the synaptic structures in both parts of the brain. A discussion is made of the plasticity of synapses during stimulation, morphological and functional relationships between hyperstriatal areas in relation to different aspects of processing and storage of visual information.
在雏鸡孵化第18天开始进行节律性视觉刺激、孵化后11 - 12小时进行闪烁刺激，以及对孵化后前两天在正常光照下饲养和在黑暗中饲养的雏鸡，对其左右半球腹侧和副纹状体中部的突触进行了形态计量分析。在超薄切片中测定了突触的数值密度、突触后增厚的平均尺寸、突触前每个活性区的突触小泡数量以及整个轴突-树突接触的平均长度。所获得的数据表明，早期视觉经验显著影响大脑这两个部位的突触结构。文中讨论了刺激过程中突触的可塑性、纹状体区域之间在视觉信息处理和存储不同方面的形态和功能关系。
