medulla sublayer M3B

ID: FBbt_00111268

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.

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'.
