Summary: Changes in reflected light associated with epileptic neuronal activity can arise from a variety of causes including fluid and ion shifts as well as increases and decreases in perfusion and oxygenation. Optical techniques have been used to map epileptic activity for several years. In this symposium we will explore the current state-of-the-art of this technique to assess the role of optical imaging in clinical epilepsy mapping. The ability of optical imaging to both localize and predict theonset of seizures will be discussed. Future directions for research will be explored.
