Summary An epilepsy patient with recurring sensorimotor seizures involving the left hand every 10 min, was imaged with a hyperspectral camera during surgery. By calculating the changes in oxygenated, deoxygenated blood, and total blood volume in the cortex, a focal increase in oxygenated and total blood volume could be observed in the sensory cortex, corresponding to the seizure‐onset zone defined by intracranial electroencephalography ( EEG ) findings. This probably reflects very local seizure activity. After multiple subpial transections in this motor area, clinical seizures abated.
