Introduction to Neurofeedback

Definition of Neurofeedback

Neurofeedback, also known as EEG biofeedback, is a type of biofeedback that uses real-time displays of brain activity to teach self-regulation of brain function. It’s a non-invasive method that allows individuals to consciously control their brain waves.

Brief History of Neurofeedback

The concept of neurofeedback has roots in the 1960s, with the pioneering work of Dr. Joe Kamiya at the University of Chicago and Dr. Barry Sterman at UCLA. Their research laid the foundation for the development of neurofeedback as a therapeutic tool.

Overview of How Neurofeedback Works

Brainwave Patterns

Our brain produces electrical signals, known as brainwaves, which can be measured using an electroencephalogram (EEG). These brainwaves vary in frequency and are associated with different states of consciousness, such as alertness, relaxation, or deep sleep.

Feedback Mechanism

In neurofeedback training, sensors placed on the scalp measure these brainwaves. The information is then fed back to the individual through visual or auditory signals. This feedback helps the individual learn to control or modify their brainwave patterns, potentially leading to improved mental performance.
