midline/intralaminar nucleus
Quick Summary
The midline/intralaminar nuclei are a group of nuclei within the thalamus, a key structure in the brain responsible for relaying neural impulses to the cerebral cortex. These nuclei are located within the internal medullary lamina and are divided into rostral (anterior) and caudal (central) groups.12
The rostral intralaminar nuclei, including the paracentral, central medial, and central lateral nuclei, are thought to be involved in arousal, awareness, executive cognitive functions, and responding to visceral pain. They receive input from arousal and pain-related brain structures and project to areas of the basal ganglia, limbic cortex, and other cortical regions.1
The caudal intralaminar nuclei, such as the centromedian (CM) and parafascicular (Pf) nuclei, have reciprocal connections with the basal ganglia and project to areas like the ventral tegmental area and amygdala. Their diverse connections suggest roles in modulating movement, regulating pain, and arousal.1
