The Version-5 Focused on the Marmoset Cerebellum
Abstract The cerebellum is essential for motor control and cognitive functioning, engaging in bidirectional communication with the cerebral cortex. The common marmoset, a small non-human primate, offers unique advantages for studying cerebello-cerebral circuits. However, the marmoset cerebellum is not well-described in published resources. In this study, we present a comprehensive atlas of the marmoset cerebellum, comprising: 1) fine-detailed anatomical atlases and surface-analysis tools of the cerebellar cortex based on ultra-high resolution ex-vivo MRI; 2) functional connectivity and gradient patterns of the cerebellar cortex revealed by awake resting-state fMRI; and 3) structural-connectivity mapping of cerebellar nuclei using high-resolution diffusion MRI tractography. The atlas elucidates the anatomical details of the marmoset cerebellum, reveals distinct gradient patterns of intra-cerebellar and cerebello-cerebral functional connectivity, and maps the topological relationship of cerebellar nuclei in cerebello-cerebral circuits.
