Neurotransmitter Receptor Influence on Behavior

1. The concentrations of noradrenaline, dopamine, and 5-hydroxytryptamine found in the optic lobes of the octopods Octopus vulgaris, Octopus macropus, and Eledone moschata were consistently higher than the amine concentrations in the optic lobes of the decapods Loligo vulgaris and Sepia officianalis. 2. The concentrations of dopamine and 5-hydroxytryptamine did not differ widely among the various ganglia of the gastropods Helix pomatia, Helix aspersa, and Aplysia limacina. 3. Acid metabolites of dopamine and 5-hydroxytryptamine were detectable in the cephalopods but not in the gastropods. 4. Monoamine oxidase inhibitors significantly increased the concentrations of amines in O. vulgaris but not in Helix pomatia or Helix aspersa.
