Bipolar cells receive synaptic input from either rods or cones, or both rods and cones, though they are generally designated rod bipolar or cone bipolar cells. There are roughly 10 distinct forms of cone bipolar cells, however, only one rod bipolar cell, due to the rod receptor arriving later in the evolutionary history than the cone receptor ...
Bipolar cells convey impulses from photoreceptors (rods and cones) to ganglion cells, [6] which in turn transport the visual signals to the brain through the optic nerve. Bipolar cells come in two varieties, having either an on-center or an off-center receptive field, each with a surround of the opposite sign. The off-center bipolar cells have ...
The horizontal cells lie in the outer part of the inner nuclear layer and possess somewhat flattened cell bodies.. Their dendrites divide into numerous branches in the outer plexiform layer, while their axons run horizontally for some distance and finally ramify in the same layer.
A retinal ganglion cell (RGC) is a type of neuron located near the inner surface (the ganglion cell layer) of the retina of the eye.It receives visual information from photoreceptors via two intermediate neuron types: bipolar cells and retina amacrine cells.
Visual phototransduction is the sensory transduction process of the visual system by which light is detected by photoreceptor cells (rods and cones) in the vertebrate retina.A photon is absorbed by a retinal chromophore (each bound to an opsin), which initiates a signal cascade through several intermediate cells, then through the retinal ganglion cells (RGCs) comprising the optic nerve.
The amacrine II cells transfer signals bidirectionally, allowing for impressive synchronization of responses from this network. [2] From this network, the bipolar cells each turn on or off to control the intensity of light perceived, and to contrast between colors. [6] Interconnectivity between Amacrine II cells [2]
