Functional Mapping for Epilepsy

Functional mapping involves neurosurgeons placing electrodes in the form of wires or flexible sheets (called strips and grids) on or in brain tissue to map the precise origin of seizures. Grid electrodes can be used both for recording and stimulating brain tissue to identify the underlying function of that region, such as language, sensation or motor function.
