The effects of melanocyte-stimulating hormone (MSH), melatonin, and Pro-Leu-Gly-NH2 on levels of general locomotor activity were investigated in hypophysectomised and intact rats. General activity was not altered by the hormones studied. Body weight, food ingestion, and water intake were also measured and found to be unchanged. The findings reduce the possibility that alterations in activity account for the behavioral changes previously observed after administration of MSH, melatonin, or Pro-Leu-Gly-NH2.
