Localization of the gastrin-releasing peptide (GRP)-like immunoreactivity in the brain ofthe Japanese quail pretreated with colchicine was investigated using anti-porcine GRP serum and anti-bombesin serum. In the hypothalamus, numerous neurons exhibiting GRP-immunoreactivity were detected in the suprachiasmatic nucleus. In the extrahypothalamus, GRP neurons were widely distributed in the telencephalon (hyperstriatum accessorium, hyperstriatum ventrale, neostriatum dorsolaterale, neostriatum

The GRP-immunoreactive fibers were seen in the nucleus ofstria terminalis oftelencephalon and in the nucleus infundibularis of the hypothalamus, where they were in close contact with the unlabeled perikarya. With the anti-bombesin serum, neurons and fibers were not immunostained throughout the brain.
