This traditional list does not accord strictly with human thalamic anatomy.

Nuclear
Nucleus (neuroanatomy)
In neuroanatomy, a nucleus is a brain structure consisting of a relatively compact cluster of neurons. It is one of the two most common forms of nerve cell organization, the other being layered structures such as the cerebral cortex or cerebellar cortex. In anatomical sections, a nucleus shows up...
groups of the thalamus
Thalamus
The thalamus is a midline paired symmetrical structure within the brains of vertebrates, including humans. It is situated between the cerebral cortex and midbrain, both in terms of location and neurological connections...
include:
- anterior nuclear group
- anteroventral nucleus
- anterodorsal nucleus
- anteromedial nucleus
- superficial ("lateral dorsal")
- medial nuclear group (or dorsomedial nucleusMedial dorsal nucleusThe medial dorsal nucleus is a large nucleus in the thalamus.It is believed to play a role in memory.-Anatomy:...
)- parvocellular partParvocellular partParvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus of the thalamus. "Parvus" means "small" in Latin, and the name "parvocellular" refers to the small size of the cell compared to the larger magnocellular cells...
- magnocellular partMagnocellular partMagnocellular 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...
- parvocellular part
- midline nuclear groupMidline nuclear groupThe midline nuclear group a region of the thalamus consisting of the following nuclei:* paraventricular nucleus of thalamus - not to be confused with paraventricular nucleus of hypothalamus* paratenial nucleus * reuniens nucleus * rhomboidal nucleus The midline nuclear group (or midline thalamic...

- centromedian nucleus
- lateral nuclear groupLateral nuclear groupThe lateral nuclear group is a collection of nuclei on the lateral side of the thalamus. According to MeSH, it consists of the following:* lateral dorsal nucleus* lateral posterior nucleus* pulvinar...

- pulvinarPulvinarThe pulvinar nuclei are a collection of nuclei located in the pulvinar thalamus. The pulvinar part is the most posterior region of the thalamus....
- lateral posterior nucleus belongs to pulvinar
- (lateral dorsal nucleus) belongs to anterior group
- pulvinar
- ventral nuclear groupVentral nuclear groupThe ventral nuclear group is a collection of nuclei on the ventral side of the thalamus. According to MeSH, it consists of the following:* ventral anterior nucleus* ventral lateral nucleus* ventral posterior nucleus...
- ventral anterior nucleusVentral anterior nucleus-Inputs and outputs:The ventral anterior nucleus receives neuronal inputs from the basal ganglia which includes the substantia nigra and the globus pallidus. It also has inputs from the cerebellum. It sends out neuronal input to the supplementary motor cortex and to primary motor...

- ventral posterior nucleusVentral posterior nucleusThe ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain.-Input and output:The ventral posterior nucleus receives neuronal input from the medial lemniscus, spinal lemniscus, spinothalamic tracts, and trigeminothalamic tract...
