General Information
Term anterior-projecting DN1p neuron ID (Ontology) FBbt:00052272 (Fly Anatomy)
Definition Adult unilateral DN1p neuron that innervates the anterior optic tubercle (AOTU) (Lamaze et al., 2018; Reinhard et al., 2022). Its projections form two loop-like structures, one around the superior lateral protocerebrum and the other at the surface of the clamp, both converging shortly before the AOTU (Lamaze et al., 2018; Reinhard et al., 2022). It also projects ventrally to the posterior lateral protocerebrum (Reinhard et al., 2022). Its input and output sites are equally distributed in all of its regions of innervation (Reinhard et al., 2022). It sends output to tubercle-bulb and tubercle-tubercle neurons in the anterior optic tubercle (Guo et al., 2018; Reinhard et al., 2022). It expresses cryptochrome (Chatterjee et al., 2018; Reinhard et al., 2022).There are two of these cells per hemisphere (Reinhard et al., 2024).[ FlyBase:FBrf0239433 FlyBase:FBrf0240295 FlyBase:FBrf0240599 FlyBase:FBrf0253505 FlyBase:FBrf0261099 ]
