Phenylethanolamine is present in the Aplysia nervous system in concentrations similar to that of octopamine. These are receptors that are very specific for phenylethanolamine, which on different neurons mediate sodium, chlorine, or potassium conductance increase responses. These observations indicate that phenylethanolamine may act as a neurotransmitter in Aplysia.
