Intralaminar nucleus

The nuclei intralaminares are a group of brain nuclei that are assigned to the unspecific thalamus ( truncothalamus ). Its largest representative is the nucleus centromedianus , which is of great importance in the unspecific excitation of the cerebral cortex by the ascending reticular activation system . He is also involved in the integration of motor impulses.

The intralaminar core group receives its afferents from the cerebellum , the spinothalamic tract , from the reticular formation, and from premotor and motor cortex areas . Efferents leave the intralaminar nuclei in the direction of the striatum and cingulate gyrus . There are also connections to other thalamic nuclei.
