Curious Minds Want to Know: The Neurofeedback Journey – An FAQ Exploration
What is neurofeedback and how does it work?
Neurofeedback, also known as EEG biofeedback, is a therapeutic intervention that provides immediate feedback from a computer-based program that assesses a person’s brainwave activity. The program then uses sound or visual signals to retrain or reorganize these brain signals. By responding to this feedback, individuals can learn to regulate their own brain activity to improve various cognitive, emotional, and physical functions.
Who discovered neurofeedback and when?
Neurofeedback has roots in the 1920s with the discovery of the electroencephalogram (EEG), but it wasn’t until the 1960s that neurofeedback began to develop as a therapy. Dr. Joe Kamiya is credited with the discovery of neurofeedback at the University of Chicago, when he demonstrated that individuals could learn to control their alpha brain waves when provided with feedback.
