Abstract

Dopamine (DA) is present in the gill of Aplysia in considerable quantity. We have investigated the possibility that DA may be an excitatory neuromuscular transmitter. Perfusion of DA through the gill elicits contraction of the same muscles as are activated by the identified motor neurons L₇ and L₉. The cholinergic motor neuron LDG₁ activates different muscles. The contractions induced by DA and three L₉ neurons but not that of L₇ are blocked by ergometrine. These results are consistent with the possibility that the neurons L₉, L_9-A and L_9-P are dopaminergic motor neurons.
