Considerable evidence suggests that rapid eye movement (REM) sleep is induced by glutamatergic activation of cholinergic cells within the pedunculopontine tegmentum (PPT). The aim of this study is to test a popular hypothesis that serotonin, norepinephrine, and adenosine act on PPT cells to regulate REM sleep. This study also tests an alternate hypothesis that serotonin may inhibit REM sleep signs by direct action on the individual REM sleep sign generators.
