The Lateralized Linguistic Cerebellum: A Review and a New Hypothesis

摘要: During the past 2 decades collaboration across disciplines and methodologic conceptual advances of contemporary neuroscience have brought about a substantial modification traditional view cerebellum as mere coordinator autonomic somatic motor functions. Growing insights in neuroanatomy its interconnections, evidence from functional neuroimaging neurophysiological research, advancements clinical experimental neuropsychology established that participates much wider range functions than conventionally accepted. This increase insight has to fore modulates cognitive functioning at least those parts brain which it is reciprocally connected. article reviews recently acknowledged role cognition addresses more detail data disclosing modulatory various non-motor language processes such lexical retrieval, syntax, dynamics. In agreement with findings indicating topographical organization cerebellar structures involved pathology we advance concept "lateralized linguistic cerebellum." our crossed cerebral diaschisis processes, reflecting depression supratentorial areas due reduced input via cerebellocortical pathways, might represent relevant pathomechanism for deficits associated pathology.
