The INL is populated by three more types of cells, in addition to some displaced RGCs. Little is known about the interplexiform cells, which are neurons with processes in both the outer plexiform layer (OPL) and IPL. In the OPL, they are presynaptic to bipolar cells. In the IPL, they are pre‐ and postsynaptic to amacrine cells, and presynaptic to bipolar cells. Thus, it is believed that they may modulate the synaptic gain between photoreceptors and their second‐order neurons. Müller cells are another class of cells found in the INL, and are the main glial cells of the retina. Müller cells are ependymoglial cells, meaning they have both a structural support and a metabolic role.
