Abstract
A study was made of brain nucleotides and glycolytic intermediates in paradoxical sleep (PS)-deprived and recovery-sleeping rats. It was observed that PS deprivation of 24 h produced a fall in glucose, glucose 6-phosphate and pyruvate in cerebral frontal lobes. After three hours of recovery sleep all values returned toward their predeprivational levels. In cerebellar hemispheres ATP was increased, while glucose 6-phosphate and pyruvate were decreased. After three hours of recovery sleep, glucose 6-phosphate was increased and pyruvate decreased, indicating restoration of glycogen and creatine phosphate respectively.
