Abstract:
Intraperitoneal injection of a brain extract obtained from paradoxical sleep-(PS) deprived donor rats resulted in a small but significant increase of PS in normal recipient rats. Brain extract of non-deprived control rats was without effect. The results provide further evidence for the existence of a PS-inducing factor accumulating in the brain during PS deprivation.
