  Purpose

Functional neuroimaging studies have shown that the cerebellum is active during cognitive performance. The investigators hypothesize that stimulation of the cerebellum with transcranial magnetic stimulation will produce brief changes in performance of the task, suggesting that cerebellar activation is necessary for normal cognitive function.
