Studies have been made on the development of the spontaneous bioelectrical activity in the brain of 13-21-day chick embryos and on the reactions of the brain to sonic and photic stimulation (single and rhythmic). It was shown that the onset of the evoked responses to afferent stimulation coincides with predominance of a periodic process in the bioelectrical activity (17-18th days of embryogenesis). The presence of ordered rhythmicity in the bioelectrical activity of the brain which coincides with a possibility of its transformation and synchronization with afferent stimuli is suggested to be an important index of the development of the brain.
已经对13至21日龄鸡胚大脑中自发生物电活动的发育以及大脑对声音和光刺激（单次和节律性）的反应进行了研究。结果表明，对传入刺激的诱发反应的开始与生物电活动中周期性过程的优势相吻合（胚胎发育的第17 - 18天）。大脑生物电活动中有序节律的存在与大脑转化并与传入刺激同步的可能性相吻合，这被认为是大脑发育的一个重要指标。
