Figure 3: Changes in cerebellar activity during learning. A. Position of the twelve coronal slices through the cerebellum, shown on a mid-sagittal anatomical image. Slice 1 is the most anterior slice. B. Functional map illustrating the location of the average activity in four subjects during the first run. The most extensively and intensely (z >6) activated region during the learning phase is in the left superior posterior cerebellum with the approximate peak activation corresponding to Talairach coordinates (-37, -63, -22) an area previously shown to be involved in visual attention(33) C. Functional map illustrating the location of the average activity in four subjects during the last run. There is a 12 fold decrease in the total area activated, and in intensity.
