Serotonin exerts its effects by acting in three basic modes: as a classical neurotransmitter, as a neuromodulator, or as a neurohormone. In a number of invertebrate species, the neural circuitry underlying the effects of serotonin has been well characterized, whereas in vertebrates, the mechanisms by… CONTINUE READING
