Male suprachiasmatic nuclei (SCN) lesioned, blinded rats were treated with chronic Methamphet-amine (MA) via the drinking water. Body temperature, wheel running, food intake and drinking activity were automatically and continuously recorded. MA induced phase-labile rhythms with periods outside the circadian range. The circadian rhythms in partially SCN-lesioned rats reappeared without phase-shifts upon withdrawal of one month of MA treatment. The MA-induced rhythms persisted during food restriction and were synchronized by the time of food access. A phase shift of food access was followed by an immediate phase shift of the rhythms. These findings suggest that 1) the MA-induced rhythms reflect an hourglass-like oscillation 2) the SCN is not essential for their induction and 3) a cycle of food restriction acts as a Zeitgeber for this type of oscillation. |
