The functional state of the rabbit brain activating system was evaluated by the activation reaction, and the thalamic inhibitory system, by the recruiting response. At the initial phase of hypoxia, excitability of the activating system was enhanced, while at the same time the eugmenting phase of the recruiting response diminished and its inhibitory phase was prolonged. At the "altitude" of about 7000 m, against the background of a gradual weakening of the ascending activating influence of the reticular formation and the hypthalamus, the recruiting response assumed the form of regular; equally negative potentials, which testifies to the activie synchronizing influence of the inhibitory system. At a "rise" to 8500 m, against the background of slow synchronized EEG waves, in most cases there was no activation reaction to the stimulation of the reticular formation and hypothalamus. Neither was there any recruiting response to the stimulation of non-specific thalamic nuclei.
通过激活反应评估兔脑激活系统的功能状态，通过募集反应评估丘脑抑制系统的功能状态。在缺氧初期，激活系统的兴奋性增强，而与此同时，募集反应的增强期减弱，抑制期延长。在约7000米的“高度”时，在网状结构和下丘脑的上行激活影响逐渐减弱的背景下，募集反应呈现出规则的、同等负电位的形式，这证明了抑制系统的积极同步影响。在“上升”到8500米时，在脑电图缓慢同步波的背景下，大多数情况下，对网状结构和下丘脑的刺激没有激活反应。对丘脑非特异性核团的刺激也没有任何募集反应。
