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.
双侧腹内侧下丘脑损伤的大鼠在高环境温度下，固定比率为64时的压杆行为减少。对于腹内侧下丘脑损伤的大鼠，在低温时未观察到显著减少。对照组在任何温度下均未出现反应抑制。腹内侧下丘脑损伤的大鼠在高温下的停顿时间表明腹内侧下丘脑损伤与环境温度存在相互作用。
