Where is the lateral geniculate body located

A lateral geniculate nucleus is located on either side of the rear end of the thalamus. All visual information leaving the retina stops at this nucleus for processing before sent to the primary visual cortex. The lateral geniculate nuclei are located beyond the optic chiasm in the visual pathway and, therefore, receive information from the opposite visual field exclusively. The lateral geniculate nucleus LGN has been the target of extensive research for a number of years.

This nucleus is organized in six layers, shaped to look very much like a finger print. The receptive fields of cells in the LGN exhibit the same concentric on-off characteristics as those of retinal ganglion cells. Four of the LGN layers parvocellular layers 3 to 6 have small receptive fields with input primarily from cones and the X-cells of the ganglion layer.

Together with the medial geniculate body , it forms the metathalamus. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Updating… Please wait.
