We present the first study of simultaneous fMRI during direct electrical stimulation in the human brain of epilepsy patients. Spatial activation patterns and strengths in fMRI maps are compared to responses from electrical recordings from intracranial electrodes placed throughout the brain. We found significant positive correlation between strength of fMRI activation and electrical activity. Potential clinical applications include using electrically stimulated fMRI to plan for epilepsy surgery.
