small field neuron of the central complex fan-shaped body columnar neuron fan-shaped body extrinsic columnar neuron 2020-09-24T14:30:40Z VFB:FBbt_00049822 FBbt:00049822 Adult fan-shaped body columnar neuron with projections to other neuropils (Scheffer et al., 2020). These are usually, if not always, unicolumnar in the fan-shaped body (Andrade et al., 2019; Hulse et al., 2021). They generally follow a nine-column fan-shaped body organization (Hulse et al., 2021). fly_anatomy.ontology input/output neuron
