本研究分析了猫在快速眼动和桥-膝-枕（PGO）睡眠过程中基底外侧杏仁核（BLA）、扣带回前部和后部（A-CG和P-CG）、背侧海马（DH）、丘脑腹前核（AVTN）和感觉运动皮层的电活动。使用眼球的外直肌（LR）的相位收缩作为分析的触发信号，进行多导记录和计算事件平均值。我们在BLA、A-CG、P-CG、DH和AVTN中观察到与REM睡眠阶段现象相关的可变振幅双相电位（200-300 ms）。这些区域的电位变化幅度总是大于膝状体的PGO活动。我们建议，记录的边缘电位导致传播的PGO活动，这种现象可能反映了边缘结构的幻觉，植物，和REM睡眠的情感成分。
We analyzed the electrical activity of the basolateral amygdala (BLA), anterior and posterior regions of the cingulate gyrus (A-CG and P-CG), the dorsal hippocampus (DH), the anterior ventral thalamic nucleus (AVTN), and the sensory motor cortex during the rapid eye movements and ponto-geniculo-occipital (PGO) activity of REM sleep in cats in chronic preparation. Polygraphic recordings and computational peri event averages using the phasic contractions of the lateral rectus muscle (LR) of the eyeball as the triggering signal of the analysis were performed. We observed biphasic potentials (200-300 ms) of variable amplitude, related to the phasic phenomena of REM sleep, in the BLA, A-CG, P-CG, DH, and AVTN. The latencies of the potentials of these regions were always greater than those of the geniculate PGO activities. We propose that the recorded limbic potentials resulted from propagation of PGO activity and that this phenomenon may reflect the limbic structure of the hallucinatory, vegetative, and emotional components of REM sleep.
