Figure 1. Schematic illustrating the inhibitory effects of serotonin (5-hydroxytryptamine, 5-HT) 1A (5-HT 1A) (red) and 5-HT 1B (blue) receptors on the normal firing and neurotransmitter release of a neuron (top).

Figure 1.

Activation of 5-HT 1A receptors results in decreased firing (middle), while activation of 5-HT 1B receptors causes decreased neurotransmitter release through actions in the presynaptic terminal (bottom).
