Ability of rats with ventromedial hypothalamic lesions to work: effects of ambient temperature.
Rats with bilateral ventromedial hypothalamic lesions decreased bar pressing at FR 64 at high ambient temperatures. No significant decrease was noted at low temperatures for VMH rats. Controls evidence no response suppression at any temperature. Pause time for the VMH rats at high temperatures suggest a VMH lesion-ambient temperature interaction.
