Special Issue Information

Dear Colleagues,

Canonically, the cerebellum is known to facilitate smooth, synchronous integration of motor functions. Recent work suggests a similar role for non-motor functions, although the cellular mechanisms underlying the cerebellar contribution to cognitive and affective processes remain unknown. The cerebellum can powerfully influence upstream brain regions involved in both cognitive and motor functions via thalamic relays. Reciprocal pontine nuclei inputs to the cerebellum allow for further integration. This feedback and integration of information from vast regions of the brain enables the cerebellum to learn, perform, and refine both motor and non-motor capabilities, making it an ideal target for novel translational and transdiagnostic treatments for diseases or events that culminate in cerebellar dysfunction. The goal of this Special Issue is to bring together novel research topics related to the contribution of abnormalities in cerebellar circuitry to disease states involving cognitive and affective dysfunction. We hope this also encourages researchers in all areas of neuroscience to critically consider the cerebellum in their current research models spanning areas of science outside motor function.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The cerebellum is commonly viewed as a structure that is primarily responsible for the coordination of voluntary movement, gait, posture, and speech. Recent research has shown evidence that the cerebellum is also responsible for cognition. We analyzed 28 participants divided into three groups (9 with normal cognition, 9 with mild cognitive impairment, and 10 with moderate/severe cognitive impairment) based on the Montreal Cognitive Assessment. We analyzed the cerebellar cortex and white matter volume and assessed differences between groups. Participants with normal cognition had higher average values in total cerebellar volume, cerebellar white matter volume, and cerebellar cortex volume in both hemispheres, but by performing the Kruskal–Wallis test, we did not find these values to be statistically significant.
