Abstract

The brainstems of 3 cats were transected at the ponto-medullary junction and the cats maintained in stable condition for periods of from 16 to 31 days. After transection, all of these cats had periods in which forebrain sensorimotor cortex, olfactory bulb, hippocampus, eye movement and lateral geniculate recordings exhibited the pattern of activity seen only in REM sleep in the intact cat. We conclude that medullary regions are not required to generate these signs of REM sleep. The pons is necessary for REM sleep and is sufficient to produce REM sleep signs in rostral as well as caudal brain regions. However, the medulla may contribute to regulation of the duration and periodicity of REM sleep.

摘要

对3只猫的脑干在脑桥延髓交界处进行横切,并将这些猫维持在稳定状态16至31天。横切后,所有这些猫都有这样的时期,即前脑感觉运动皮层、嗅球、海马体、眼球运动和外侧膝状体记录显示出仅在完整猫的快速眼动睡眠中才出现的活动模式。我们得出结论,延髓区域并非产生快速眼动睡眠这些体征所必需的。脑桥对于快速眼动睡眠是必要的,并且足以在脑前部以及脑后部区域产生快速眼动睡眠体征。然而,延髓可能有助于调节快速眼动睡眠的持续时间和周期性。
