title: Paradoxical sleep rebound without previous debt: the effect of minute doses of clonidine in man.
abstract: This report describes an experimental condition in which clonidine administration does not modify paradoxical sleep (PS) directly, but is followed by a secondary rebound. After oral consumption of minute doses of clonidine (CLN), 12 subjects showed no direct effect of CLN, but showed a significant increase of PS production in the following placebo night. Four other subjects experienced a decrease of PS under CLN and no rebound the next night. In addition, these four subjects had mechanisms of slow wave sleep production significantly weaker than the first 12 subjects.
