Abstract:
:We investigated temporal relationships among EEG theta frequency, eye movement (EM) burst and phasic surge of arterial pressure (AP) during rapid eye movement (REM) sleep in six rats. Changes in EEG theta frequency, EM number, mean AP (MAP) and heart rate (HR) during 1 s bins were obtained with reference to the onset of the EM bursts. The acceleration of EEG theta frequency preceded both the EM burst and the phasic increases of AP. The increase of MAP was closely correlated with the theta frequency but not the EM number during the period of EM burst. The possible involvement of the limbic system for the generation of phasic surge in AP during REM sleep is discussed.
