Lateral Geniculate Nucleus

The lateral geniculate nucleus (LGN) is the primary relay center for visual information received from the retina of the eye. The LGN is found inside the thalamus of the brain.

The LGN receives information directly from the ascending retinal ganglion cells via the optic tract and from the reticular activating system. Neurons of the LGN send their axons through the optic radiation, a direct pathway to the primary visual cortex. In addition, the LGN receives many strong feedback connections from the primary visual cortex. In mammals, including humans, the two strongest pathways linking the eye to the brain are those projecting to the LGNd (dorsal part of the LGN in the thalamus), and to the superior colliculus (SC).

Famous quotes containing the word nucleus:

    You know that the nucleus of a time is not
    The poet but the poem, the growth of the mind
    Of the world, the heroic effort to live expressed
    As victory. The poet does not speak in ruins
    Nor stand there making orotund consolations.
    He shares the confusions of intelligence.
    Wallace Stevens (1879–1955)
