  2. Retina bipolar cell - Wikipedia

    en.wikipedia.org/wiki/Retina_bipolar_cell

    Rod bipolar cells do not synapse directly on to ganglion cells. Instead, rod bipolar cells synapse on to a Retina amacrine cell, which in turn excite cone ON bipolar cells (via gap junctions) and inhibit cone OFF bipolar cells (via glycine-mediated inhibitory synapses) thereby overtaking the cone pathway in order to send signals to ganglion ...

  3. Bipolar neuron - Wikipedia

    en.wikipedia.org/wiki/Bipolar_neuron

    A bipolar neuron, or bipolar cell, is a type of neuron characterized by having both an axon and a dendrite extending from the soma (cell body) in opposite directions. These neurons are predominantly found in the retina and olfactory system. [ 1 ]

  4. Photoreceptor cell - Wikipedia

    en.wikipedia.org/wiki/Photoreceptor_cell

    The photoreceptors (rods and cones) transmit to the bipolar cells, which transmit then to the retinal ganglion cells. Retinal ganglion cell axons collectively form the optic nerve, via which they project to the brain. [8] The rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter ...

  5. Retinal ganglion cell - Wikipedia

    en.wikipedia.org/wiki/Retinal_ganglion_cell

    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.

  6. Layer of rods and cones - Wikipedia

    en.wikipedia.org/wiki/Layer_of_rods_and_cones

    The elements composing the layer of rods and cones (Jacob's membrane) in the retina of the eye are of two kinds, rod cells and cone cells, the former being much more numerous than the latter except in the macula lutea. Jacob's membrane is named after Irish ophthalmologist Arthur Jacob, who was the first to describe this nervous layer of the ...

  7. Visual phototransduction - Wikipedia

    en.wikipedia.org/wiki/Visual_phototransduction

    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.

  8. Retinal implant - Wikipedia

    en.wikipedia.org/wiki/Retinal_implant

    Diagram of the eye, the retina, and location of the various retinal implants. Retinal layers, from bottom to top: retinal pigment epithelium (RPE), photoreceptors (PR), horizontal cells (HC), bipolar cells (BC), amacrine cells (AC), ganglion cells (RGC), nerve fiber layer (RNFL).
