  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

    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 ...

  4. Inner nuclear layer - Wikipedia

    en.wikipedia.org/wiki/Inner_nuclear_layer

    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.

  5. Retinal waves - Wikipedia

    en.wikipedia.org/wiki/Retinal_waves

    Bipolar cells differentiate later than amacrine and ganglion cells, which could be the cause for this change in wave behavior. [4] The change from cholinergic mediation to glutamatergic mediation occurs when bipolar cells make their first synaptic connections with ganglion cells. [ 7 ]

  6. Metabotropic glutamate receptor 6 - Wikipedia

    en.wikipedia.org/wiki/Metabotropic_glutamate...

    These cells form synapses with photoreceptor cells, and detect the neurotransmitter glutamate via a GPCR signal transduction cascade. The glutamate receptor mGluR6 is located post-synaptically at the tips of the bipolar cell dendrites, and is responsible for initiating a signaling cascade that ultimately controls gating of the TRPM1 channel.

  7. Retinal summation - Wikipedia

    en.wikipedia.org/wiki/Retinal_summation

    Retinal summation describes the relationship between different types of cells in the retina: cone photoreceptor cells, bipolar cells, and ganglion cells.With high retinal summation, a large number of photoreceptor cells converge on a smaller number of bipolar cells in transferring their signals to ganglion cells.

  8. Midget cell - Wikipedia

    en.wikipedia.org/wiki/Midget_cell

    In many cases, they are connected to midget bipolar cells, which are linked to one cone each. [ 1 ] These neurons show roughly circular receptive fields with antagonistic center and surround; this property is known as spatial opponency and these neurons are typically divided into ON- or OFF-center, depending on whether they are excited or ...

  9. Amacrine cell - Wikipedia

    en.wikipedia.org/wiki/Amacrine_cell

    Amacrine cells operate at the inner plexiform layer (IPL), the second synaptic retinal layer where bipolar cells and retinal ganglion cells form synapses.There are at least 33 different subtypes of amacrine cells based just on their dendrite morphology and stratification.
