We measured changes in the frequency of hypothalamic self-stimulation in cats during their stays in a normal-oxygen nitrogen-oxygen environment under a pressure of 6 kg/cm2. A 200-300% increase in the frequency of self-stimulation was observed during the initial exposure. A depression of the reaction with a subsequent normalization by the third day took place after decompression. The second exposure led to an adaptation of the organisms to the effect of the elevated partial pressure of nitrogen. It is suggested that the changes in the self-stimulation reaction are connected with the "narcotic" effect of nitrogen under elevated pressures.
我们测量了猫在6千克/平方厘米压力下处于常氧-氮-氧环境期间下丘脑自我刺激频率的变化。在初次暴露期间，观察到自我刺激频率增加了200%-300%。减压后，反应出现抑制，到第三天恢复正常。第二次暴露导致机体适应了氮气分压升高的影响。有人认为，自我刺激反应的变化与高压下氮气的“麻醉”作用有关。
