Lateral geniculate nucleus
Lateral geniculate nucleus
The Lateral geniculate nucleus (pronounced: lat-er-al jen-ick-yoo-late new-klee-us) is a significant structure in the visual system. It is a relay center in the thalamus for the visual pathway and is a crucial part of the brain involved in processing visual information.
Etymology
The term "Lateral geniculate nucleus" is derived from the Latin words 'latus' meaning 'side', 'geniculum' meaning 'little knee', and 'nucleus' meaning 'kernel'. The term refers to the structure's position on the side of the thalamus and its bent, knee-like shape.
Function
The Lateral geniculate nucleus receives a major sensory input from the retina. The retina sends information about light and dark, color, and movement to the Lateral geniculate nucleus via the optic nerve. The Lateral geniculate nucleus then sends this information to the primary visual cortex, which is responsible for processing visual information.
