Abstract

Feeding-related neuronal activity of monkey amygdalar glucose-sensitive and morphine-sensitive cells was investigated during a task that required bar-pressing to obtain food. Both glucose-sensitive and morphine-sensitive cells, located mostly in the centromedial part of the amygdala, decreased firing during the bar-press period more often than insensitive cells. Naloxone attenuated the decrease in activity during the bar press period. The results suggest involvement of these glucose- and morphine-sensitive cells in the control of food acquisition behavior.

摘要

在一项需要按压杠杆获取食物的任务中，对猴子杏仁核葡萄糖敏感和吗啡敏感细胞的进食相关神经元活动进行了研究。葡萄糖敏感和吗啡敏感细胞大多位于杏仁核的中央内侧部分，与不敏感细胞相比，它们在按压杠杆期间放电频率降低的情况更为常见。纳洛酮减弱了按压杠杆期间的活动减少。结果表明，这些葡萄糖敏感和吗啡敏感细胞参与了食物获取行为的控制。
