A horizontal cell is a neuron that laterally connects other neurons in the inner nuclear layer (INL) of the retina. Targeting of retinal neurons to the appropriate lamina is vital to establish the architecture of the retina. retinal horizontal cell positioning laminar positioning of retinal horizontal cell horizontal cell localisation localization of cell
