Phasic changes in muscular and reflex activity during non-REM sleep.

摘要: Abstract The occurrence of phasic reductions EMG activity during non-rapid eye movement (non-REM) sleep in man and cat are described, an analysis the phenomenon is presented. Twelve subjects (ten male, two female) slept a total 107 nights laboratory. Standard recordings were taken electroencephalographic (EEG), electrooculographic (EOG), electromyographic (EMG) activity. Suppressions observed all stages non-REM sleep, but occurred with greatest frequency 2 4. suppressions averaged 250 msec duration exhibited higher 10 min immediately prior to REM periods than subsequent periods. relationship between H reflex was examined three (two males, one who recorded 9 nights. In addition standard EEG, EOG, derivations, elicited by electrical stimulation posterior tibial nerve, from soleus muscle, viewed on oscilloscope. EMG, muscle action potentials magnetic tape. it found that whenever stimulus coincidental reduction, response invariably inhibited. observation verification human subject related recent data cat, application this physiological event studies mentation discussed.
