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 ...
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 ...

The lateral dorsal nucleus is a nucleus of the thalamus. It is the most anterior of the dorsal lateral nuclei. [1] It is also known as the dorsal superficial nucleus. [2]
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]
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.
The lateral nuclear group consists of the following: lateral dorsal nucleus; lateral posterior nucleus; pulvinar nuclei; The lateral region of the thalamus which results from trisection by the internal medullary lamina also includes the ventral nuclear group and the lateral and medial geniculate nuclei.
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.
