  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 optic tract is a continuation of the optic nerve that relays information from the optic chiasm to the ipsilateral lateral geniculate nucleus (LGN), pretectal nuclei, and superior colliculus. [14] The optic tract represents the first stage in the visual pathway in which visual information is transferred in a homonymous nature. [ 15 ]

  4. 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 ...

  5. Optic tract - Wikipedia

    en.wikipedia.org/wiki/Optic_tract

    It is a continuation of the optic nerve that relays information from the optic chiasm to the ipsilateral lateral geniculate nucleus (LGN), pretectal nuclei, and superior colliculus. [ 1 ] It is composed of two individual tracts, the left optic tract and the right optic tract, each of which conveys visual information exclusive to its respective ...

  6. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The lateral geniculate body; The optic radiation; The visual cortex; The visual association cortex. These are components of the visual pathway, also called the optic pathway, [23] that can be divided into anterior and posterior visual pathways. The anterior visual pathway refers to structures involved in vision before the lateral geniculate ...

  7. Optic nerve - Wikipedia

    en.wikipedia.org/wiki/Optic_nerve

    Most of the axons of the optic nerve terminate in the lateral geniculate nucleus from where information is relayed to the visual cortex, while other axons terminate in the pretectal area [7] and are involved in reflexive eye movements. Other axons terminate in the suprachiasmatic nucleus and are involved in regulating the sleep-wake cycle. Its ...

  8. Parvocellular cell - Wikipedia

    en.wikipedia.org/wiki/Parvocellular_cell

    In neuroscience, parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus. Their name comes from Latin parvus 'small', due to the small size of the cell compared to the larger magnocellular cells. Phylogenetically, parvocellular neurons are more modern ...

  9. Koniocellular cell - Wikipedia

    en.wikipedia.org/wiki/Koniocellular_cell

    Schematic diagram of the primate LGN. Koniocellular neurons not labeled, but are present between the layers. In neuroscience, koniocellular cells, also called K-cells, are relatively small neurons located in the koniocellular layer of the lateral geniculate nucleus (LGN) within the thalamus of primates, including humans.
