Facilitation of thermoregulatory heating behavior by single cortical spreading depression in the rat.

abstract：:Unlike rats, Siberian hamsters exhibit seasonal changes in energy balance that are controlled by the photoperiod (daylength). In Siberian hamsters, body weight and fat, and food intake peak in long, summer-like days and reach nadirs in short, winter-like days. The purpose of the present experiments was to test whether...
