Neurofeedback is a non-invasive, evidence-based form of personalized brain training that alters brain wave activity. It has been found to be immensely helpful in alleviating symptoms of ADHD, anxiety, PTSD, and traumatic brain injury, while also enhancing cognitive performance. This innovative approach, also known as EEG neurofeedback training, relies on real-time feedback from an electroencephalogram (EEG) to measure the brain’s electrical activity.

Neurofeedback therapy offers immediate information about brain wave activity, enabling individuals to learn self-regulation of brain function. Sensors are placed on the scalp to monitor brain waves, with the data displayed on a screen. Through repeated sessions, individuals can learn to control their brainwaves, leading to improved brain function and mental health.

Neurofeedback training is akin to a fitness regimen for the brain. Just as physical exercise strengthens muscles, neurofeedback strengthens neural pathways, enhancing cognitive performance and emotional resilience. Whether it’s reducing anxiety, improving attention, or achieving peak performance, neurofeedback treatment offers a powerful tool for brainwave training and cognitive enhancement, making it a valuable asset in the toolkit of neurofeedback practitioners.

How Does Neurofeedback Work?

The brain produces five types of brainwaves—delta, theta, alpha, beta, and gamma—each associated with different states of consciousness and brain activity. For instance, alpha waves are prominent when a person is relaxed, while beta waves are linked to mental and physical activity. EEG neurofeedback training focuses on these brainwaves, providing real-time feedback to help individuals learn to regulate their brain activity.

Neurofeedback operates on a bidirectional approach, meaning it can teach the brain to better regulate itself. Sensors on the scalp measure brainwave activity during a session, displaying the data on a monitor. Observing these patterns helps individuals learn to control their brainwaves, enhancing brain function.

This personalized brain training, using specific neurofeedback protocols, is tailored to each individual’s unique brain activity, making it an effective method for brain training and cognitive enhancement.

A Brief History of Neurofeedback
