Distribution of cholecystokinin (CCK) in the rat lower brain stem nuclei.
The cholecystokinin (CCK) concentration in individual brain stem nuclei of rat was determined using the Palkovits punch method19 and the CCK RIA3, CCK has a unique distribution in the brain stem, unlike other neuropeptides and biogenic amines8,19. In general, the CCK levels in the brain stem are 5-20% of rat cerebral cortex. The colliculi, midbrain central gray, nucleus of the solitary tract, and the interpeduncular nucleus had the highest CCK content (2.7-1 ng CCK mg protein).
