Abstract

Reward-related neuronal activity and its modulation by morphine and naloxone was investigated by extracellular single neuron recording and electrophoretic application of drugs in the lateral hypothalamus, during operant feeding of the monkey. Morphine-sensitive neurons responded more often during bar press and ingestion-reward phase. Naloxone blocked only ingestion-reward responses, especially the inhibitory ones. The results suggest that the central opiate system can be involved in reward-related neuronal responses in the lateral hypothalamic area of the monkey.
