An Anatomical and Connectivity Atlas of the Marmoset Cerebellum

As one of the smallest non-human primates, the common marmoset provides many advantages in the study of the anatomy and the functions of cerebello-cerebral circuits. However, the cerebellum of the marmoset is far from being well described in published resources.

In this study, we present a comprehensive atlas of the marmoset cerebellum in three parts: 1) fine-detailed anatomical atlases and surface-analyzing tools of the cerebellar cortex, based on ultra-high resolution ex-vivo MRI; 2) functional-connectivity gradients of the cerebellar cortex, based on awake resting-state fMRI; and 3) structural-connectivity based mapping of the cerebellar nuclei, based on high-resolution diffusion tractography.
