Bipolar cells in the retina

WebBipolar cells are interneurons in the retina (), which transfer visual information from photoreceptors (rods and cones; Photoreceptors) to amacrine (Retinal direction selectivity: Role of starburst amacrine cells) and ganglion cells (Retinal ganglion cells).Bipolar cells consist of multiple (9–12) subtypes that differ in their morphology, synaptic connectivity, … WebRetinal Circuitry (Parallel Pathways) The retina is a highly organized, layered structure. The information begins at the receptors and flows through a second layer of cells, called bipolar cells, and then continues through a third layer of cells, called ganglion cells.
