The stimulation, in the encéphale isolé cat, of the basal preoptic hypnogenic area be brief electrical pulses evokes bilaterally an extracellular positive (P) field potential of 20 to 60 msec duration in the brain stem and thalamic activating ascending reticular system. The properties of this P wave have led to consider it as the extracellular and abbreviated counterpart of an hyperpolarizing postsynaptic inhibitory process which, by the functional depression it exerts on the arousal system… CONTINUE READING
