Mia medullary intrinsic neuron vGlutMinew2 FBbt:00110096 Medulla intrinsic neuron which arborizes in medulla layer M1 and then projects along one medulla column without forming many lateral branches until it reaches layers M7 to M9, where it arborizes extensively. In M1, it contacts 14-15 columns in both the anterior-posterior and dorsal-ventral axes. In M7-M9 it innervates four to five columns in the dorsal-ventral axis (Jagadish et al., 2014). It is postsynaptic to the R7 and R8 photoreceptors (Jagadish et al., 2014). It is a glutamatergic neuron (Raghu and Borst, 2011). VFB:FBbt_00110096 fly_anatomy.ontology vGlutMinew2 Minew2
