“…These are related to mem ory processes [Wimersma Greidanus et al, 1983;de Wied et al, 1984;Dantzer et al, 1988], passive avoid ance behavior [de Wied et al, 1984;Soderstcn et al, 1985Soderstcn et al, , 1986Veldhuis et al, 1987], thermoregulation [Kasting et al, 1982;Cooper et al, 1987;Pittman et al, 1988;Kasting, 1989] and blood pressure [Pittman et al, 1982;Sodersten et al, 1983]. Furthermore, several studies have indicated that there are strong in teractions between catecholamines and vasopressin [Kovacs et al, 1977[Kovacs et al, , 1979ade Wied and Bohus, 1978;Marchand and Hagino, 1982;Buijs et al, 1984;van Heuven-Nolsen and Versteeg, 1985;Nakada and Nakai, 1985]. Based on the strong resemblance of the distribution of extrahypothalamic VTi fibers in rep tiles and mammals, particularly the innervation of limbic structures, the midbrain dopaminergic cell groups and the nucleus of the solitary tract, it is con ceivable that reptilian vasotocinergic systems also play a role in memory and in behavioral and auto nomic functions.…”
