In rats, arginine-vasopressin (AVP) iontophoretically applied to lateral septal neurons activated by fimbria stimulation produced a decrease in the amplitude of the fimbria-evoked field response and a decrease in the frequency of fimbria-evoked action potentials. A second group of rats, treated with α-methyl-p-tyrosine, showed a significantly smaller decrease in responses after AVP iontophoresis, suggesting an interaction between catecholamines and AVP at the synaptic level.
