The basal ganglia function from thalamus is controlled by ?
Ans. is 'a' i.e., Anterior nucleusMotor nuclei (ventral anterior and ventral lateral) of thalamus relay and process messages from basal ganglia (especially globus pallidus) and cerebellum to motor and premotor coex.From functional point of view, thalamic nuclei are divided into :?A) Specific sensory nuclei (relay nuclei) :- These nuclei receive all sensory afferents from ascending pathways and project to the somatosensory coex. These include ventroposterior nucleus and medial & lateral geniculate bodies.B) Association nuclei :- These nuclei have reciprocal connections with the association areas of the cerebral coex and therefore help in integration of different type of sensory information. These nuclei include the lateral group of nuclei (Pulvinar, lateral dorsal, lateral posterior nuclei) and pa of medial dorsal nucleus.C) Nonspecific nuclei :- These nuclei also receive sensory information but project to the coex in a diffuse manner. Therefore they seem to be involved in the arousal induced by sensory stimuli. These nuclei are intralaminar and reticular nuclei.D) Motor nuclei :- There nuclei relay and process messages from the basal ganglia and cerebellum to motor and premotor coex. These nuclei are ventral anterior and ventral lateral nuclei.
