Sleep: Control of the paradoxical episode?
Cooling of the medial aspects of the midbrain tegmentum produces high voltage EEG rhythms and behavioral depression. This same procedure carried out in cats pretreated with parachlorophenylalanine between post-drug hours 20 and 60 produces a state exhibiting the tonic and phasic EEG, EOG, EMG and gross behavioral criteria of the paradoxical episode of sleep.
