It was found that "increasing movement extent was associated with parallel increases of rCBF in bilateral basal ganglia (BG; putamen and globus pallidus) and ipsilateral cerebellum."
In more recent research, subcortical regions (those lying below the cerebral cortex such as the putamen and the caudate nucleus ) as well as the pre-motor areas ( BA 6 ) have received increased attention.
Muscimol was injected into various parts of the basal ganglia, and it was found that "the learning of new sequences became deficient after injections in the anterior caudate and putamen, but not the middle-posterior putamen."
Now it is known that not only the basal ganglia and caudate affect category learning. citation Role in "hate circuit" Recent, tentative studies have suggested that the putamen may play a role in the so-called " hate circuit" of the brain.
