The development of EEG was studied in normal and undernourished white and black hooded rats, aged 9-30 days. Undernutrition of the young was accomplished by underfeeding the mothers with restricted amounts of a standard laboratory food from the 7th day after conception until the 21st day after birth. Bipolar EEG recordings were made from the sensorimotor cortex and from the visual cortex in rats with chronically implanted electrodes. The EEG was recorded, stored on magnetic tape and analyzed for amplitude distributions and frequency spectra. During the recording 3 behavioural states (defined on the basis of behavioural criteria) were distinguished.
对9至30日龄的正常和营养不良的白色及黑色帽状大鼠的脑电图（EEG）发育情况进行了研究。幼鼠的营养不良是通过从受孕后第7天至出生后第21天给母鼠喂食限量的标准实验室食物来实现的。对长期植入电极的大鼠，从感觉运动皮层和视觉皮层进行双极脑电图记录。脑电图被记录下来，存储在磁带上，并分析其振幅分布和频谱。在记录过程中，区分出3种行为状态（根据行为标准定义）。
