Previous investigations have demonstrated that two regions in the right cerebellum, one located superiorly in hemispheral lobule VI/Crus I and another located inferiorly in hemispheral lobule VIIB/VIIIA, are activated during verbal working memory performance. On the basis of functional neuroimaging patterns of activation, as well as known cortico-pontine and ponto-cerebellar projections, the superior region has been hypothesized to contribute to the articulatory control system of working memory whereas the inferior region has been linked to the phonological store. The present study used event-related fMRI and individual estimates of hemodynamic response for both the cerebellum and neocortex to test this model and characterize the task phase specific cerebro-cerebellar activations for a Sternberg verbal working memory task. Results demonstrated that the right superior cerebellum showed the strongest …
