Towards an fMRI validation of our previous fNIRS-based explorations of cerebellar activity [Rocco et al. EMBC 2021], we introduce here a joint sequential fNIRS/fMRI study based on finger tapping that provides both finer time and space granularities for the assessment of BOLD effect in the cerebellum.
