The EEG and impulse activity of the neurons of the cerebral cortex and other structures of the brain were studied in the dynamics of hypoxic influence. In the initial phase of hypoxia (2000-6000 m), activation of the EEG and impulse discharge of neurons set in; in this case EEG activation arose earlier and was more pronounced. In the second phase of hypoxia (7500-10,000 m), the EEG changed in the direction of a reorganization of the frequency spectrum from one rhythm to another - from fast to slow activity of the type of delta waves. At this time the impulse activity was gradually suppressed, and the cortical neurons exhibited higher sensitivity to hypoxia and were inhibited earlier than the cells of the hypothalamus and medulla oblongata.
在缺氧影响的动态过程中，对大脑皮层及大脑其他结构的神经元的脑电图（EEG）和冲动活动进行了研究。在缺氧的初始阶段（海拔2000 - 6000米），脑电图激活和神经元冲动放电开始出现；在这种情况下，脑电图激活出现得更早且更明显。在缺氧的第二阶段（海拔7500 - 10000米），脑电图朝着频谱从一种节律重组为另一种节律的方向变化——从快波活动转变为δ波类型的慢波活动。此时，冲动活动逐渐受到抑制，皮层神经元对缺氧表现出更高的敏感性，并且比下丘脑和延髓的细胞更早受到抑制。
