Neurofeedback is biofeedback for the brain. Small sensors rest on your scalp and read your brainwave activity. Nothing is put into your body.
The software gives your brain moment-to-moment feedback through sound and music. Over time, your brain learns to settle into calmer, more flexible patterns on its own.
Most people find sessions deeply relaxing. You sit back in a comfortable chair, listen, and let the training do its work.
