Serotonergic neurons are present in all phyla that possess nervous systems. In most of
these phyla, serotonin modulates important behaviours, including feeding, sexual and …

Serotonin-containing neurosecretory neurons in the first abdominal ganglion (A1 5-HT cells)

Crayfish escape from threats by either giant neuron-mediated “reflex” tail flexions that occur
with very little delay but do not allow for much sensory guidance of trajectory or by “nongiant” …

Giant interneurones mediate a characteristictail flip'escape response of the crayfish,
