  2. Retina horizontal cell - Wikipedia

    en.wikipedia.org/wiki/Retina_horizontal_cell

    Horizontal cells span across photoreceptors and summate inputs before synapsing onto photoreceptor cells. [1] [2] Horizontal cells may also synapse onto bipolar cells, but this remains uncertain. [1] [4] There is a greater density of horizontal cells towards the central region of the retina.

  3. Amacrine cell - Wikipedia

    en.wikipedia.org/wiki/Amacrine_cell

    Like horizontal cells, amacrine cells work laterally, but whereas horizontal cells are connected to the output of rod and cone cells, amacrine cells affect the output from bipolar cells, and are often more specialized. Each type of amacrine cell releases one or several neurotransmitters where it connects with other cells. [2]

  4. Retina bipolar cell - Wikipedia

    en.wikipedia.org/wiki/Retina_bipolar_cell

    The horizontal cells introduce lateral inhibition to the dendrites and give rise to the center-surround inhibition which is apparent in retinal receptive fields. The amacrine cells also introduce lateral inhibition to the axon terminal, serving various visual functions including efficient signal transduction with high signal-to-noise ratio. [3]

  5. Retina - Wikipedia

    en.wikipedia.org/wiki/Retina

    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.

  6. Inner nuclear layer - Wikipedia

    en.wikipedia.org/wiki/Inner_nuclear_layer

    In the anatomy of the eye, the inner nuclear layer or layer of inner granules, of the retina, is made up of a number of closely packed cells, of which there are three varieties: bipolar cells, horizontal cells, and amacrine cells.

  7. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    Schematic diagram of the human eye. It shows a horizontal section through the right eye. The eye is made up of three coats, or layers, enclosing various anatomical structures. The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the eye and support the deeper structures.

  8. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    In addition, other neurons in the retina, particularly horizontal and amacrine cells, transmit information laterally (from a neuron in one layer to an adjacent neuron in the same layer), resulting in more complex receptive fields that can be either indifferent to color and sensitive to motion or sensitive to color and indifferent to motion.

  9. Retinal regeneration - Wikipedia

    en.wikipedia.org/wiki/Retinal_regeneration

    The signal goes first to the bipolar and horizontal cells (yellow layer), then to the amacrine cells and ganglion cells (purple layer), then to the optic nerve fibres. The signals are processed in these layers. First, the signals start as raw outputs of points in the rod and cone cells.
