Microdisplay Monitors Brain Activity

A thin film that combines an electrode grid and LEDs can both track and produce a visual representation of the brain’s activity in real time. The device is designed to provide neurosurgeons visual information about a patient’s brain to monitor brain states during surgical interventions to remove brain lesions including tumors and epileptic tissue.
