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.
Amacrine cells also produce lateral inhibition to bipolar cells [18] and ganglion cells to perform various visual computations including image sharpening. [19] The final visual signals will be sent to the thalamus and cerebral cortex , where additional lateral inhibition occurs.
Horizontal cells provide inhibitory feedback to rod and cone photoreceptors. [1] [2] They are thought to be important for the antagonistic center-surround property of the receptive fields of many types of retinal ganglion cells. [3] Other retinal neurons include photoreceptor cells, bipolar cells, amacrine cells, and retinal ganglion cells.
The amacrine cells are placed in the inner part of the inner nuclear layer, and are so named because they have not yet been shown to possess axis-cylinder processes. Their dendrites undergo extensive ramification in the inner plexiform layer.
Retina amacrine cells, particularly narrow field cells, are important for creating functional subunits within the ganglion cell layer and making it so that ganglion cells can observe a small dot moving a small distance. [1] Retinal ganglion cells collectively transmit image-forming and non-image forming visual information from the retina in the ...
AII (A2) amacrine cells are a subtype of amacrine cells. Amacrine cells are neurons that exist in the retina of mammals to assist in interpreting photoreceptive signals. AII amacrine cells serve the critical role of transferring light signals from rod photoreceptors to the retinal ganglion cells (which contain the axons of the optic nerve).
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception.
The inner plexiform layer is an area of the retina that is made up of a dense reticulum of fibrils formed by interlaced dendrites of retinal ganglion cells and cells of the inner nuclear layer. Within this reticulum a few branched spongioblasts are sometimes embedded.
