Laser beams to the brain reveal seizures in real time

University of Florida researchers have used a laser beam to detect areas of a mouse brain involved in an epileptic seizure.
The laser-induced PAT (photoacoustic tomography) procedure involves shining a laser beam through the skull. Cortical areas involved in the seizure absorb more energy, which is converted to sound vibrations that can be detected by an ultrasonic transducer, allow for mapping cortical activity.
