REM
main point: 不同睡眠清醒状态下,人的神经兴奋特点
结构:
介绍REM以及和清醒状态的相似性
介绍PGO spikes 不只是在REM中
指出PGO和EMPS存在各种状态中,作为一个警觉反应
段落:
1. REM : best known as the sleep phrase -> intense dreams
● contrast to slow-wave(low frequcny, high-amplitude)->dreamless
● similar with the waking state :
- A. EEG indicates: high-frequency, low-amplitude
- B. neuro activity in various subunits, hippocampus
- C. brain temperature rise
2. PGO spike not unique to REM
● previous: PGO occur almost uniquely in REM SLEEP
● accidental discovery: accidentally struk+ cat's slow-wave sleep=>PGO spikes
● subsequent study: boths sound and touch could produce PGO in REM/slow-wave sleep
3. reevaluate the EMPs: a general alterting response
● previous: EMPs in the waking state
● now: EMPs& PGO spikes are general altering response in REM, slow-wave sleep, and wakefulness
● experiment: a cat in a darkened cage+ odd of tuna-> EMPs+PGO |
