Attention and working memory (WM) are processes that enable the efficient prioritization or storage of a subset of available information. A substantial body of work has sought to determine the specific brain structures that support attention and WM. To date, this literature has predominantly focused on the contributions of a limited set of cortical areas referred to as the dorsal attention network (DAN). The cerebellum, a subcortical structure traditionally implicated in motor control, has received scant consideration as a locus of attentional control, despite findings of robust anatomical and functional connectivity between cerebellum and DAN areas. In this talk, I will present the findings of a series of functional magnetic resonance imaging (fMRI) experiments aimed at elucidating the role the cerebellum in attention and WM. Taken together, the results of these experiments argue for the reconceptualization of the DAN as a cortico-cerebellar network.
