Serotonergic input on identified command neurons in Helix.
In Helix, serotonin evokes long-lasting alteration of activity of withdrawal triggering neurons. Cell bodies of these neurones are surrounded by a dense network of serotonin-containing fibres without any synaptic membrane specializations, which confirm the suggestion on the non-synaptic, modulatory action of serotonin on the withdrawal command elements.
