Keeping yourself in shape is important. Often overlooked, your brain can be trained just like you would a bicep. Mendi makes it possible, using lab-tested tech with a combo of brain-monitoring wearable and an app. Unlike common neurofeedback sensors that measure with EEG, Mendi uses a proprietary technology to deliver research-grade measurements. That data is then used in the app to control a game, flooding the prefrontal cortex with blood and oxygen as progress is made. The result is improved cognitive performance in as little as five minutes, 2-3 times a week — or probably less time than you spend exercising the rest of your body.
