adult fan-shaped body layer 4 tangential neuron primary interneuron dopaminergic PPM3 neuron mFB neuron of the dopaminergic PPM3 cluster 2013-04-05T04:03:58Z fly_anatomy.ontology Based on cell numbers and innervation pattern, the mFB neurons from Liu et al. (2012) probably correspond to both PPM3 layer 4 types (FB4L, FB4M) from Hulse et al. (2021). FBbt:00110325 VFB:FBbt_00110325 Adult dopaminergic PPM3 neuron whose main projection innervates fan-shaped body layer 4, with a large-field arborization pattern (Liu et al., 2012; Hulse et al., 2021).
