In Helix, activation of an identified serotonin‐containing neurone produces a slow, markedly voltage‐sensitive, depolarizing synaptic potential in another identified neurone, the A neurone. Accommodation of impulse activity in the A neurone observed with repetitive applied constant‐amplitude pulses is markedly reduced by activating the serotonin neurone. Activation of the serotonin neurone also prolongs the duration of the A neurone action potential.
