title: Catecholaminergic neurons of treefrog isthmotrigeminal tegmentum.
abstract: Neurons that take up 3H-noradrenaline were detected, by autoradiography, around the ventral tip of the isthmic nucleus in treefrogs. No uptake was detected in the adjacent pretrigeminal nucleus, suggesting that this is not homologous to the locus coeruleus.
