  2. Lateral geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Lateral_geniculate_nucleus

    In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...

  3. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    The lateral geniculate nucleus (LGN) is the nucleus in the thalamus that receives visual information from the retina and sends it to the visual cortex via optic radiations. A lesion of this nucleus produces moderately to completely congruent visual field defects. [20]

  4. Visual cortex - Wikipedia

    en.wikipedia.org/wiki/Visual_cortex

    The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 , Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19 ).

  5. Optic radiation - Wikipedia

    en.wikipedia.org/wiki/Optic_radiation

    In neuroanatomy, the optic radiation (also known as the geniculocalcarine tract, the geniculostriate pathway, and posterior thalamic radiation) are axons from the neurons in the lateral geniculate nucleus to the primary visual cortex. The optic radiation receives blood through deep branches of the middle cerebral artery and posterior cerebral ...

  6. Magnocellular cell - Wikipedia

    en.wikipedia.org/wiki/Magnocellular_cell

    Magnocellular cells, also called M-cells, are neurons located within the magnocellular layer of the lateral geniculate nucleus of the thalamus. The cells are part of the visual system. They are termed "magnocellular" since they are characterized by their relatively large size compared to parvocellular cells.

  7. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    For the visual system, for example, inputs from the retina are sent to the lateral geniculate nucleus of the thalamus, which in turn projects to the visual cortex in the occipital lobe. [32] Similarly the medial geniculate nucleus acts as a key auditory relay between the inferior colliculus of the midbrain and the primary auditory cortex.

  8. Topographic map (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Topographic_map_(neuroanatomy)

    The ganglion cells of the retina project in an orderly fashion to the lateral geniculate nucleus of the thalamus and from there to the primary visual cortex(V1); adjacent spots on the retina are represented by adjacent neurons in the lateral geniculate nucleus and the primary visual cortex.
