WebThese layers contain ganglion cell bodies, their axons and dendrites, structures especially affected by glaucoma. 36 When RNFL is removed, the remaining layers form the Ganglion Cell–Inner Plexiform Layer, as mentioned above. In our study, we also examined changes in the relationship between FAZ and GCC relative to refraction groups. WebBased on their projections and functions, there are at least five main classes of retinal ganglion cells: Midget cell (parvocellular, or P pathway; P cells) Parasol cell (magnocellular, or M pathway; M cells) Bistratified cell …

Photoreceptors synapse onto bipolar cells in the retina. There are two types of bipolar cells: OFF and ON. These cells respond in opposite ways to the glutamate released by the photoreceptors because they express different glutamate receptors. Like photoreceptors, the bipolar cells do not fire action potential … See more The front of the eye consists of the cornea, pupil, iris, and lens. The cornea is the transparent, external part of the eye. It covers the pupil and the iris and is the first location of light … See more The photoreceptors are the specialized receptors that respond to light. There are two types of photoreceptors: rods and cones. Rods are … See more The center-surround structure of the receptive field is critical for lateral inhibition to occur. Lateral inhibition is the ability of the sensory systems … See more Each bipolar and ganglion cell responds to light stimulus in a specific area of the retina. This region of retina is the cell’s receptive field. … See more WebCells in the eye called rods and cones are primarily responsible for detecting light. They send signals to the brain through retinal ganglion cells (RGCs) so the brain can form our perception of images. But our eyes do more than help create images of our surroundings. dogadjaji u becu
