Electroencephalography (EEG) is widely used to characterize the temporal patterns of electrical activity, primarily associated with neocortex. Traditionally, the sensitivity of EEG to cerebellar activity has been considered limited with the electrical potentials assumed to stem from cortical pyramidal cells. This study leverages recent work examining the structure, organization, and synchrony of purkinje neurons to promote local field potentials measured by EEG. In conjunction with high fidelity EEG recording and source imaging analysis we examined the feasibility of using current EEG systems to characterize cerebellar function in a series of simple motor tasks. Distributed source imaging analysis revealed consistent task-related cerebellar activity across subjects whose time course was consistent with cerebellar involvement for the control of voluntary movement. The results demonstrate the feasibility of using current EEG systems and source imaging techniques to resolve activity in the cerebellum that is distinct from task-related activity in cortex.
