title: Modification of the pattern of central neurons by sensory inputs from the reproductive organs in Aplysia depilans L.
abstract: In the abdominal ganglion of Aplysia a number of motoneurons regulating visceral organs reacted to the stimulation of the reproductive organs. The response was mostly biphasic and often delayed. The multifunctional interneuron I (cell L10) reacted to the stimulation of the reproductive organs with burst firing, followed by an inhibitory phase. The interneuron II, involved in the regulation of visceral functions, was also activated during stimulation of the reproductive organs and its burst-pattern could be identified on a number of other neurons. Several members of the neurosecretory cell group reacted to the stimulation of reproductive organs. The response was, as a rule, biphasic and similar to the hormone action, long-lasting. Three further cells (near the cell L12, above the cell L21, and the neuron between R2 and R7 with unknown function) showed a stereotyped response to the stimulation of the reproductive organs. All the neurons reacting to the stimulation of the reproductive organs also received inputs from the cardiorenal system. The data support the existence of common networks composing variable units in the regulation of visceral functions of gastropods.
