General Information

Term

medulla directional M6 local neuron

ID (Ontology)

FBbt:00111066 (Fly Anatomy)

Definition

Local neuron that is restricted to layer 6 of the medulla. Its soma is in the medial or dorsal regions of the lateral cell body rind. In contrast to non-directional M6 local neurons, dendrites and axon terminals are segregated. Putative dendrites are found in the anterior region of the M6 layer and axons at the posterior one. Individual neurons vary greatly on how many columns they cover, with a range between 65 and 157. This neuron type includes glutamatergic neurons, among other neurotransmitters.[ FlyBase:FBrf0226257 ]

Also Known As

"directional M6-LN"

Comment

The glutamate neurotransmitter was assessed by labelling cells with an antibody against vGlut (FBgn0031424) (Chin et al., 2014).
