Details of lophophore innervation and cerebral ganglion in Plumatella repens and Fredericella sultana. a, b, cerebral ganglion and lophophoral nerves in P. repens (view from above) (staining with antibodies against serotonin); c, cerebral ganglion and accumulations of neurons at the tentacle bases in P. repens (lateral view) (staining with antibodies against FMRFamide); d, cerebral ganglion and accumulations of neurons at the tentacle bases in F. sultana (lateral view) (staining with antibodies against FMRFamide). Abbreviations: an, accumulations of neurons at tentacle bases; bn, bipolar neurons situated near oral and lophophore arms tentacle bases; co, commissure; g, cerebral ganglion; inp, nerve plexus of introvert; lh, lophophore nerve tract (horn); n, neuropil of cerebral ganglion.
