Nuclei caudales intralaminares thalami

Intralaminar caudal group of high nuclei., CM-PF complex

The caudal intralaminar thalamus nuclei, a group to hay. and one to the left, are deposited in the inner white matter layer of the thalamus (lamina medullaris thalami interna).

The group includes: the CM nucleus (nucleus CentroMedianus) and the PF nucleus (nucleus ParaFascicularis).

The nuclei receive signals from the cerebellum, from the back horn of the spinal cord (nociception), from several brainstem nuclei and not least from cholinergic, noradrenergic and serotoninergic units.

The nucleus parafascicularis has contact with virtually the entire cerebral cortex and partly with the striatum.
The center medianum contacts primarily the striatum. The striatum, in turn, connects to the thalamus and on that way to the somato-motor cortex.

This thalamo-striatal connection provides an important meeting and coordination site for the activities of the two major subcortical motor controllers: the cerebellum and basal ganglia , as well as short contact routes to motor areas of the cerebral cortex.

The CM-PF complex is responsible for the bulk of the signal flow from the thalamus to the striatum (the thalamo-striatal projections)
