adult fan-shaped body delta neuron pontine neuron P2 2010-10-19T05:57:01Z FBbt:00007524 Adult fan-shaped body delta neuron that connects adjacent columns of the same layer of the fan-shaped body (Hanesch et al., 1989; Young and Armstrong, 2010). PFS2 FlyBrain_NDB:10252 pontine fiber system 2 See Figure 9 of Hanesch et al. (1989). According to Scheffer et al. (2020) and Hulse et al. (2021) hemibrain papers, all bicolumnar pontine neurons are separated by half the width of the FB (i.e P1 type), meaning that this cell type may not exist (but could just be absent from the hemibrain fly). fly_anatomy.ontology VFB:FBbt_00007524 fan-shaped body intrinsic neuron
