What is the nucleus of lateral genikulat?
The lateral geni -core (LGN) is part of thalamus, which serves as a primary center for processing visual information. This could be considered the main relay center from the retina to the part of the brain that integrates and responds to visual stimuli. In humans and other mammals, visual projection to the lateral geniculation core is one of the two strongest ways that connect the eye to the brain. LGN damage can result in a certain degree of blindness.
Origin is a Latin term for the knee. On the basis of its appearance of similar knees, the lateral genius core was named as such. It is located on the dorsum thalamus, so it is part of the central nervous system. The right and left hemispheres of the brain have a single lateral geni -core. Neuropil is a aty of gray matter that has non -perelinated nerve fibers and relatively thin cell bodies. Usually, the side genius core has six different layers. The inner two layers are called magncellular layers, while the outer four layers withThey call parvocellular layers.
Magncellular layers have large cells called magniecellular (m) ganglium cells that receive input from peripheral retina, and parvocellular layers have small cells called parvocellular (P) ganglium cells that receive input from central retina or fovea. While p gangli cells are sensitive to color and can perceive a high level of detail, M cells are insensitive colors and details. Although the cells are weak in color and detail detection, they are highly sensitive to movement.
The retina of each eye projects the neurons into the lateral genius core of the right and left hemispheres. However, each LGNly gets information from half of each field of view. This is due to crossing or deciphering axons from the inner or nasal sides of the retina. Axons from the outer or temporary halves of the retina remain on the same side.
Visual information from lateral genius coreEducation of projects to the visual cort of both hemispheres as optical radiation. The left half of the field of view is perceived by the right hemisphere, while the right half is perceived by the left hemisphere due to the above decussion. When the signals reach the primary visual bark located on both hemisphere, the brain is able to reconstruct the image collected by the retinal cells. Through the transmission of the signal from the retina to LGN to the visual bark, people are able to experience conscious visual perception.
