Thalamic Nuclei
NUCLEUS | MAJOR IMPUT | MAJOR OUTPUT | FUNCTIONS | FUNCTIONAL CLASS | EXTRA INFORMATION |
---|---|---|---|---|---|
Anterior | from mammillary body of the hypothalamus | cingulate gyrus of limbic lobe | mediates visceral, emotional information | specific, limbic | |
Ventral Anterior | globus pallidus, substantia nigra and intralaminar and midline thalamic nuclei | premotor and primary motor cortices | motor | specific motor | |
Ventrolateral | Contralateral cerebellar hemisphere through superior cerebellar penduncle, globus pallidus | primary motor cortex | motor: coordinates basal ganglia with cerebellum | specific motor | |
Ventral Posterior (lateral and medial) | spinothalamic tracts and medial leminscus (medial=trigeminal nerve) | postcentral gyrus | somatosensory | specific, sensory | |
Lateral Geniculate | retinal ganglion cells | Lingual and cuneate gyri of the occipital lobes | vision | specific, sensory | |
Medial Geniculate | Inferior colliculus | terminate in the auditory cortex | auditory | specific, sensory | |
Dorsomedial | Prefrontal cortex, substantia nigra, amygdala, hypothalamus | prefrontal cortex, amygdala | limbic | specific, limbic | |
Pulvinar | primary associational visual cortex | inferior parietal cortex (association cortex) | important contributions to language formulation, language processing | specific, associational | |
Centromedian | globus pallidus, vestibular nucleus, superior colliculus, reticular formation, spinal cord, motor / premotor cortices | basal ganglia and thalamus | modulates excitability of cortex (cognitive) and overall functions of basal gaglia (sensorimotor) | non-specific | |
Reticular | thalamocortical projections | thalamic nuclei and reticular formation | integrates and regulates thalamic neuronal activity | non-specific |
