Bipolar and ganglion cells

WebThe brown cells are the bipolar neurons and the large orange structures are the cell bodies of the ganglion cells. The red colored layer at the top represents the choroid and the top purple layer the sclera. The bipolar neurons, so named because they have one dendrite and one axon, are the connections between the photoreceptors and the ganglion ... WebThe respective midget bipolar cells are almost solely synaptic upon single midget ganglion cells (Fig. 14), except in the very central fovea where a few midget bipolar synapses are shared with neighboring midget ganglion cells because of the crowding of neurons and neuropil (Fig. 13).
