Abstract:The ‘mirror technique’ was used in immuno-electron microscopy to examine the synaptic relationships between neuronal structures containing catecholamines and cholecystokinin (CCK) in the caudal part of the dorsomedial medulla oblongata in the rat, using antisera against tyrosine hydroxylase and CCK. CCK-immunoreactive axon terminals made synaptic contacts with catecholaminergic neurons. Some of these catecholaminergic neurons contained CCK.
Keywords:dorsomedial medulla oblongata   catecholamine   cholecystokinin   coexistence   synapse   solitary tract
