The cerebellum has been implicated in affective and attentional processes, but little is known about corresponding neural signatures. We investigated early and late components of event-related potentials (ERPs) to emotionally arousing pictures, with and without competing attentional tasks, in a patient with an ischemic right posterior cerebellar infarction, at two months post infarct and two year follow-up. The early posterior negativity (EPN) response to highly arousing emotional cues in the competing visual attention condition revealed that the augmentation over occipital areas, as typically seen in normals, was absent post-infarct but was restored after two years. The late positive potentials (LPP) response to highly arousing emotional cues showed augmentation over frontal areas post-infarct, and over centro-parietal regions after two years. These ERP findings suggest a specific pattern of disruption of neural function associated with emotional-behavioral disturbances following cerebellar lesions, which can revert to normal with long term recovery.
