medulla sublayer M3A

ID: FBbt_00111267

Distal sublayer of the medulla layer M3, proximal to layer M2. It is defined by the extent of the arborization of Dm3 neurons.

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'.
