Mt4

ID: FBbt_00003840

Medulla tangential neuron that principally extends along the border of the serpentine layer and medulla layer M8 for approximately their anterior two-thirds. It shows extensive fine and bleb-like arborizations in medulla layers M8 and M9, but only fine arborizations in the serpentine layer and layer M6. It is a cholinergic neuron (Varija Raghu et al., 2011). There are around 25 of these cells per hemisphere (Nern et al., 2025).

The neurotransmitter was assessed by co-labelling cells with a Cha-GAL4.7.4 driver (FBtp0014830) and an anti-ChAT antibody (Varija Raghu et al., 2011). Pre- versus postsynaptic innervation judged by scoring of terminal morphology from figures in Fischbach and Dittrich (1989) as assessed by FlyBrain Neuron DB.
