Siberian hamsters were maintained in a short-day photoperiod (8 h light/day) at 15 degrees C; body temperature (Tb) was telemetrically monitored at 10-min intervals over the course of 4 months. Animals manifesting repeated torpor bouts (Tb < 30 degrees C) were subjected to lesions of the paraventricular nucleus (PVN) or a sham operation. In the 8 weeks after surgery, 67% of the animals with complete bilateral ablation of the PVN failed to express torpor; circadian Tb rhythms, as determined by periodogram analysis, were normal in all operated and sham-operated animals. Body mass did not change in PVN-ablated animals that continued to express torpor; in contrast, rapid and sustained increases in body mass were manifested by all hamsters that terminated expression of torpor. Expression of torpor is attenuated in the absence of the PVN; it is suggested that the PVN influences torpor indirectly by regulating body mass or the availability of metabolic fuels.
