Abstract

Lateral hypothalamic intracranial self-stimulation was studied before and after paradoxical sleep deprivation (PSD) induced by the platform method. Rats were assigned to two counterbalanced groups where the sequence order of experimental (small platform) and control (large platform) treatments was permuted. In contrast with previous findings significant changes in the response rates for intracranial self-stimulation were not observed after PSD. Ineffectiveness and nonspecific effects of the treatment are ruled out as the cause for our findings. An hypothesis is suggested that the effect of PSD upon intracranial self-stimulation could be dependent of the brain electrode location. © 1984.
