The device looks like a headband and is equipped with sensors that measure brain activity. By shining near-infrared light into the skull and measuring the intensity of light reflected back, oxygen levels corresponding to brain activity can be recorded. The device, originally developed by Drexel’s biomedical engineers to monitor the brain of patients under anesthesia, serves as a controller for the Drexel-developed video game Lazybrains.
