DN2

ID: FBbt_00003630

Adult DN period neuron whose medium-sized cell body is located posteriolaterally in the dorsal superior brain (Helfrich-Forster, 2005). A dendritic lateral branch projects into the superior lateral protocerebrum, forming a characteristic loop towards, but not reaching, the ipsilateral anterior optic tubercle (Reinhard et al., 2022). It also has an axonal branch extending contralaterally, via the middle dorsal commissure, terminating in the superior medial protocerebrum just before reaching the contralateral DN2 cell bodies (Reinhard et al., 2022). It expresses Allatostatin C and Proctolin (Reinhard et al., 2024). There are 2 of these cells per hemisphere (Helfrich-Forster, 2005; Ma et al., 2021).

One cell is CRY negative, the other is weakly CRY positive, but they do not have morphological differences (Reinhard et al., 2022).
