General Information
Term medulla sublayer M3B ID (Ontology) FBbt:00111268 (Fly Anatomy)
Definition Proximal sublayer of the medulla layer M3, proximal to layer M3A. It is defined by the extent of the arborization of Dm12 and Dm20 neurons.[ FlyBase:FBrf0228639 ]
Comment In the literature there are two methods for describing spatial location of neurons in the visual system: distal-proximal (e.g. Fischbach and Dittrich, 1989), and medial-lateral (e.g. Ito et al., 2014), both meaning outer and inner, and refer to the distance of a structure along the visual pathway relative to the center of the brain. Currently we will adopt the classical 'distal-proximal'.
