Non-invasive measures of brain activity provide valuable insights to the functioning of the brain and the mental processes underlying perception and cognition. Until recently, the most accessible method to measure brain activity was via expensive, lab-based electroencephalography (EEG) systems operated by trained researchers or technicians.
Decades of EEG research have revealed much about how brain activity is modulated from sleep to awake states, during cognitive and perceptual tasks, and after various training paradigms, as well as how these dynamics change during typical and atypical development. However, use of EEG has, until now, largely been restricted to controlled environments with time- and labor-intensive studies using research-grade equipment with relatively small sample sizes.
