The initial phase of hypoxia effect involves activation of the EEG (2000---6000 m) and unit impulse activity (7500--10 000 m). The 7500--10 000 m induced a change towards a predominant slow rhythm of the delta-type while the unit impulse activity gradually diminished, the cortical neurons displaying a higher hypoxia sensitivity and an earlier suppression than the cells of the hypothalamus and the medulla. In all phases of the hypoxia effect the EEG waves showed a greater sensitivity to the rapid peripheral signals than the unit impulse activity of the cortex and other brain structures.
缺氧效应的初始阶段涉及脑电图（海拔2000 - 6000米）和单位冲动活动（海拔7500 - 10000米）的激活。海拔7500 - 10000米时，脑电图向以δ波为主的慢节律转变，而单位冲动活动逐渐减弱，与下丘脑和延髓的细胞相比，皮质神经元对缺氧更敏感，抑制也更早出现。在缺氧效应的所有阶段，脑电图波比皮质和其他脑结构的单位冲动活动对快速外周信号更敏感。
