medulla layer M2

ID: FBbt_00003751

Second most lateral layer of the medulla. It is defined by the distal extent of the distal lamina monopolar neuron L2 arborization (Fischbach and Dittrich, 1989).

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'.
