Pm4 [FBbt_00111282]
Proximal medullary amacrine neuron that branches at the proximal surface of the medulla. It covers around 10-20 columns with its pre- and post-synapses mostly in layers M8-M9 (Nern et al., 2025). It occupies a central intracolumnar position. It is GABAergic (Davis et al., 2020). There are around 75-85 of these neurons per hemisphere (Nern et al., 2025).
