EEG reactions to afferent stimuli and the driving responses (DR) to photic flickering with 1-15 sec frequency were studied in different brain structures of rabbits lacking visual experience (from the 8th to the 23rd and from the 57th to the 90th day of life). The orienting reaction in the first few days of the light regime is characterized by enhanced motor and respiratory components and is not extinguished for a long time when the stimulus is repeated. It is attended with theta-rhythm in the hippocampus EEG and desynchronized activity in the neocortical areas. DR is characterized by spatial-temporal dissociation; its development is markedly retarded in the cortical projection zone of the visual system, and of the archicortex structures, in the dentate fascia, as compared with the hippocampus proper, the midbrain reticular formation and the auditory cortex. The DR index equals the level of that of the control animals after nine to twelve days of their life in the light. The results obtained attest that the observed differences in the changes of the functional characteristics of the hippocampus and other brain structures depend on the mode of the central organization of the reaction, whose correlate is the studied EEG-parameter.
在缺乏视觉经验的家兔（出生第8至23天以及第57至90天）的不同脑结构中，研究了脑电图（EEG）对传入刺激的反应以及对频率为1至15秒的光闪烁的驱动反应（DR）。在光照期的最初几天，定向反应的特点是运动和呼吸成分增强，当刺激重复时，这种反应长时间不会消失。此时海马EEG出现θ节律，新皮质区域出现去同步化活动。DR的特点是时空分离；与海马本身、中脑网状结构和听觉皮质相比，其在视觉系统的皮质投射区以及古皮质结构、齿状筋膜中的发育明显延迟。DR指数在动物光照生活9至12天后等于对照动物的水平。所得结果证明，海马和其他脑结构功能特性变化中观察到的差异取决于反应的中枢组织模式，其相关因素是所研究的EEG参数。
