Administration of carbachol into the lateral ventricle and suprachiasmatic nucleus (SCN) produces dose-dependent phase shifts in the circadian rhythm of locomotor activity

The cholinergic agonist, carbachol, induces phase-dependent shifts in the timing of the circadian rhythm of locomotor activity (CRLA). The effects of carbachol injections into the lateral ventricles of hamsters were compared between circadian times that produce phase delays vs. phase advances in the...
