bipolar cell उदाहरण वाक्य
उदाहरण वाक्य
- AII-amacrine cells capture rod bipolar cell input and redistribute it to cone bipolar cells since rod-driven bipolar cells do not synapse on ganglion cells.
- Amacrine cells with extensive dendritic trees are thought to contribute to inhibitory surrounds by feedback at both the bipolar cell and ganglion cell levels.
- Amacrine cells operate at the inner plexiform layer ( IPL ), the second synaptic retinal layer where bipolar cells and retinal ganglion cells form synapses.
- In 1891 Santiago Ram�n y Cajal described slender horizontal bipolar cells he had found in an histological preparation of the developing marginal zone of lagomorphs.
- The basic circuitry of the retina incorporates a three-neuron chain consisting of the photoreceptor ( either a cone ), bipolar cell, and the ganglion cell.
- Bipolar cells have a two processes extending from the cell body and multipolar cells have three or more processes extending towards and away from the cell body.
- In retinal ganglion cells ( see below ), this area of the retina would encompass all the photoreceptors, all the bipolar cells, horizontal cells, and amacrine cells.
- Absorption of a photon will hyperpolarize the photoreceptor and therefore result in the release of " less " glutamate at the presynaptic terminal to the bipolar cell.
- The rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter glutamate to bipolar cells at its axon terminal.
- On the other hand, binding of glutamate to a metabotropic receptor results in a hyperpolarization, so this bipolar cell will depolarize to light as less glutamate is released.
