August 1, 2013—Though EEG (Electroencephalography) has been around for decades, now, new technology allows us to detect and measure brain activity with a lightweight headset and mobile phone. National Geographic Emerging Explorer and entrepreneur Tan Le demonstrates how her company’s EEG headset and software can be used for a variety of research purposes.
