descending neuron of the posterior brain DNp33 obsolete antennal mechanosensory and motor center D1 projection neuron 2014-11-14T17:34:49Z true AMMC-D1 PN fly_anatomy.ontology FBbt:00110978 AMMC-D1 neuron Obsoleted due to equivalence with DNp33 (Sturner et al., 2025 - FlyBase:FBrf0262850). Projection neuron whose cell body is located in the posterior brain, close to the superior posterior slope. It projects ipsilaterally to the posterior side of AMMC zone D, branching to form postsynaptic terminals in zones B, C, D and E. It then passes through the posterior side of the gnathal ganglion, extending into the dorsolateral region of the ventral nerve cord.
