A COMMON NETWORK OF FUNCTIONAL AREAS FOR ATTENTION AND EYE-MOVEMENTS

Functional magnetic resonance imaging (fMRI) and surface-based represe ntations of brain activity were used to compare the functional anatomy of two tasks, one involving covert shifts of attention to peripheral visual stimuli, the other involving both attentional and saccadic shif ts to the same stimuli. Overlapping regional networks in parietal, fro ntal, and temporal lobes were active in both tasks. This anatomical ov erlap is consistent with the hypothesis that attentional and oculomoto r processes are tightly integrated at the neural level.
