“Think of a factory,” says Sherlin. “If all the workers are broken into little pods and they’re all doing unique things at unique times, that’s the explicit system. On an EEG, it shows up as beta. Replace those pods with a giant assembly line, one where the work is extremely rhythmic, fluid, and collaborative—aimed at a collective goal—that’s the implicit system. It’s usually denoted by a low alpha/high theta wave.”
