General Information
Term medulla intrinsic neuron Mi15 ID (Ontology) FBbt:00111285 (Fly Anatomy)
Definition Medulla intrinsic unicolumnar neuron whose primary neurite splits in the M1 layer, sending vertical branches as far as the M7 layer (Takemura et al., 2013; Takemura et al., 2015; Kind et al., 2021). A process also extends from the distal medulla into the first optic chiasma, where it receives around half of its photoreceptor input (Kind et al., 2021). In central columns, these cells selectively receive input from R8, rather than R7 photoreceptors, but selectivity is not maintained in Mi15 cells of the dorsal rim area (Kind et al., 2021). It seems to be both cholinergic and dopaminergic (Davis et al., 2020).[ FlyBase:FBrf0222324 FlyBase:FBrf0230092 FlyBase:FBrf0244935 FlyBase:FBrf0252485 ]
Also Known As "medullary intrinsic neuron Mi15" ; "Mi15"
