M. Garzon et al., NEOCORTICAL AND HIPPOCAMPAL ELECTRICAL-ACTIVITIES ARE SIMILAR IN SPONTANEOUS AND CHOLINERGIC-INDUCED REM-SLEEP, Brain research, 766(1-2), 1997, pp. 266-270
Neocortical and hippocampal EEG power spectra obtained during REM-like
. sleep induced by unilateral carbachol microinjections (0.01 M, 0.02
M and 0.2 M; volume 20 nl) into the ventral part of the nucleus reticu
laris pontis oralis have been compared with EEG power spectra obtained
during spontaneous REM sleep. Our findings indicate that neocortical
and hippocampal electrical activities during the REM-like state genera
ted by carbachol delivery in this pontine region mimic those present i
n spontaneous REM sleep. (C) 1997 Elsevier Science B.V.
