Intralaminar nuclei of thalamus

Intralaminar Nuclei of Thalamus

The Intralaminar nuclei of thalamus are a group of thalamus nuclei that are found within the internal medullary lamina. They play a significant role in the arousal and consciousness system and are involved in the integration of sensory and motor information.

Intralaminar nuclei of thalamus

Anatomy

The intralaminar nuclei are located in the internal medullary lamina, a Y-shaped layer of white matter in the thalamus. They are divided into several subnuclei, including the centromedian nucleus, the parafascicular nucleus, and the central lateral nucleus.

Function

The intralaminar nuclei are involved in several important functions. They play a role in the arousal and consciousness system, and are involved in the integration of sensory and motor information. They also have connections with the basal ganglia, and are involved in the regulation of movement.

Clinical Significance

Damage to the intralaminar nuclei can result in a variety of neurological disorders. For example, lesions in these nuclei have been associated with Parkinson's disease, Huntington's disease, and Alzheimer's disease.
