These findings yield insights into the structural connectivity of the cerebellum as relates to the uniquely human process of language comprehension. Changes in understanding language and/or language expression (like speaking or writing). We found that (a) working memory, motor activity, and language comprehension activated partially overlapping but mostly unique subregions of the cerebellum (b) the linguistic portion of the cerebello-thalamo-cortical circuit was more extensive than the linguistic portion of the cortico-ponto-cerebellar tract (c) there was a frontal-lobe bias in the connectivity from the cerebellum to the cerebrum (d) there was some degree of specificity and (e) for some cerebellar tracts, individual differences in picture identification ability covaried with fractional anisotropy metrics. Functional imaging data and diffusion-weighted imaging data from the Human Connectome Project (HCP) were analyzed. (b) An extra-axial tumor such as an meningioma pushes the whole cortex down and may cover and partially infiltrate eloquent areas.Lesions like a cavernoma (c) and a metastasis (d) may displace the CST fibres in an unpredicted trajectory. The goal of this study was to identify language-sensitive regions of the cerebellum then map the structural connectivity profile of these regions. (a) Coronar cut illustrating CST fibres originating from M1 in an healthy brain. Preoperative functional neuroimaging and. Neurobiological models of receptive language have focused on the left-hemisphere perisylvian cortex with the assumption that the cerebellum supports peri-linguistic cognitive processes such as verbal working memory. Localization of brain function is a fundamental requisite for the resection of eloquent-area brain tumors.
