The thalamus (pl.: thalami; from Greek θάλαμος, "chamber") is a large mass of gray matter on the lateral walls of the third ventricle forming the dorsal part of the diencephalon (a division of the forebrain).
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]It acts in concert with the anterior nuclei of thalamus.
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 ...

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.
The axons of second-order neurons ultimately synapse on neurons in the ventral posterior lateral nucleus (VPL) of the thalamus after coursing in the spinal lemniscus. After this, the 3rd order neuron fibers traverse the internal capsule and the corona radiata, ultimately synapsing in the post central gyrus (somatosensory cortex). The location ...
The medial dorsal nucleus (or mediodorsal nucleus of thalamus, dorsomedial nucleus, dorsal medial nucleus, or medial nucleus group) is a large nucleus in the thalamus. [ 1 ] [ 2 ] It is separated from the other thalamic nuclei by the internal medullary lamina .
