“Whenever you encounter stimuli or have a thought,” explains Sherlin, “the brain has an electrical response. EEG measures those responses down to the 1/1000 of a second range, which allows us to track how the brain changes across time. When someone is decision making—and this can be an athlete solving a physical problem or an artist solving an aesthetic one—we can see everything that leads up to a decision, the decision itself, and everything that happens as a result. No other technology can do that.”
