The present study reports on the modification of the intracranial pressure (ICP) during rapid eye movements (REM) sleep in seven chronic cats. 1. REM sleep episodes were characterized by a succession of short lasting (9 +/- 4 seconds) oscillations of the ICP. Peaks amplitude represented a hundred percent increase of the pressure as compared to its resting level. 2. These oscillations either arose from an ICP level similar to that recorded during the preceding slow wave sleep period or were seen to overide a wave of raised ICP that lasted throughout the REM period. 3. Eighty eight percent of the phasic oscillation coincided with a burt of eye movement characteristic of REM sleep. 4. Cerebral pulse wave amplitude can vary for identical ICP mean value in the course of a same REM period.
本研究报告了七只慢性猫在快速眼动（REM）睡眠期间颅内压（ICP）的变化情况。1. REM睡眠阶段的特征是ICP出现一系列持续时间较短（9±4秒）的振荡。峰值幅度相较于其静息水平，压力增加了100%。2. 这些振荡要么源于与前一个慢波睡眠阶段记录的ICP水平相似的水平，要么被观察到叠加在整个REM阶段持续升高的ICP波上。3. 88%的相位振荡与REM睡眠特有的一阵眼球运动同时出现。4. 在同一个REM阶段过程中，相同的平均ICP值下，脑脉搏波幅度可能会有所变化。
