Evoked activity of neurons in the parietal associative cortex in response to adequate and electric stimulations of the thalamic radiation fibers was studied during different phases of sleep. The number of responding neurons decreased during slow--wave and, particularly, during paradoxical sleep. With transition from phase to phase, responsiveness changed mainly in polysensory neurons which gave variable responses with long latencies. Mechanisms of change of responsiveness during the two phases appear to be different. Reliable increase of the inhibitory pause in responses during slow-wave sleep and its decrease during paradoxical sleep may indicate a strengthening of mechanisms of reciprocal inhibition during the first phase, and their weakening during the second phase.
在睡眠的不同阶段，研究了顶叶联合皮质中神经元对丘脑辐射纤维的适宜刺激和电刺激的诱发活动。在慢波睡眠期间，尤其是在异相睡眠期间，反应性神经元的数量减少。随着睡眠阶段的转换，反应性主要在多感觉神经元中发生变化，这些神经元以较长潜伏期给出可变反应。两个阶段反应性变化的机制似乎不同。慢波睡眠期间反应中抑制性暂停的可靠增加以及异相睡眠期间的减少，可能表明在第一阶段相互抑制机制增强，而在第二阶段则减弱。
