Feeding-related activity of glucose- and morphine-sensitive neurons in the monkey amygdala.
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.
