What is Subcortical Aphasia about?

## Purpose of review: Subcortical structures have long been thought to play a role in language processing. increasingly spirited debates on language studies, arising from as early as the nineteenth century, grew remarkably sophisticated as the years pass. in the context of non-thalamic aphasia, a few theoretical frameworks have been laid out. the disconnection hypothesis postulates that basal ganglia insults result in aphasia due to a rupture of connectivity between broca and wernicke's areas. a second viewpoint conjectures that the basal ganglia would more directly partake in language processing, and a third stream proclaims that aphasia would stem from cortical deafferentation. on the other hand, thalamic aphasia is more predominantly deemed as a resultant of diaschisis. this article reviews the above topics with recent findings on deep brain stimulation, neurophysiology, and aphasiology. ## Recent findings: The more recent approach conceptualizes non-thalamic aphasias as the offspring of unpredictable cortical hypoperfusion. regarding the thalamus, there is mounting evidence now pointing to leading contributions of the pulvinar/lateral posterior nucleus and the anterior/ventral
