Introduction to Neurofeedback
Definition of Neurofeedback
Neurofeedback, also known as EEG biofeedback, is a therapeutic intervention that uses real-time displays of brain activity—most commonly electroencephalography (EEG)—to teach the brain to self-regulate its functions. It’s a type of biofeedback, a method that enables an individual to learn how to change physiological activity for the purposes of improving health and performance.
The Connection Between Neurofeedback and Biofeedback
While biofeedback targets various physiological functions such as heart rate and muscle tension, neurofeedback specifically focuses on the brain’s electrical activity. By monitoring brain waves, neurofeedback allows individuals to understand their mental state and learn how to manipulate their brain activity for better performance and well-being.
Overview of the Neurofeedback Process
The neurofeedback process begins with an initial assessment to establish a baseline of the individual’s brain activity. Then, using an EEG device, the individual’s brain waves are monitored in real-time during neurofeedback sessions. The individual receives feedback—usually visual or auditory signals—based on their brain activity, and learns to control and alter their brain waves.
Understanding Brain Waves and Neurofeedback
Types of Brain Waves
Delta
Delta waves are the slowest brain waves, typically associated with deep sleep and healing.
Theta
Theta waves occur during light sleep or deep relaxation. They’re linked to creativity, emotional connection, and intuition.
Alpha
Alpha waves are present during relaxed, calm states of mind. They’re associated with mindfulness and meditation.
Beta
Beta waves dominate our normal waking state, associated with active thinking, problem-solving, and concentration.
Gamma
Gamma waves are the fastest brain waves, linked to higher cognitive functions, information processing, and learning.
The Role of EEG in Monitoring Brain Activity
EEG, or electroencephalography, is a non-invasive method used to record electrical patterns in the brain. It’s crucial in neurofeedback as it provides real-time feedback about the brain’s activity, allowing the individual to learn how to regulate their brain waves.
The Importance of Immediate Feedback
Immediate feedback is essential in neurofeedback. It allows the individual to understand their current state of brain activity and learn to manipulate their brain waves in real-time, leading to improved self-regulation of brain functions.
The Neurofeedback Session
Preparing for a Session
Setting up the EEG Equipment
Before a neurofeedback session, the EEG equipment is set up. This involves placing sensors on the scalp to monitor brain activity.
Establishing Baseline Brain Activity
The first step in a neurofeedback session is to establish a baseline of the individual’s brain activity. This provides a reference point for future sessions and helps identify any irregularities in brain wave patterns.
Real-Time Feedback Mechanisms
Visual Signals
During a neurofeedback session, visual signals—such as changes in a video game display—are often used to provide feedback based on the individual’s brain activity.
Auditory Signals
Auditory signals, such as changes in the pitch or volume of a sound, can also be used as feedback in neurofeedback sessions.
Learning to Control and Alter Brain Waves
The ultimate goal of neurofeedback is to learn to control and alter brain waves. By responding to the feedback provided, individuals can learn to manipulate their brain activity, leading to improved mental performance and well-being.
Applications of Neurofeedback
Treating ADHD with Neurofeedback
Neurofeedback has been used as a non-pharmacological treatment for Attention Deficit Hyperactivity Disorder (ADHD). By training the brain to increase beta waves (associated with focus) and decrease theta waves (associated with daydreaming), neurofeedback can help alleviate symptoms of ADHD (source).
Neurofeedback for Depression and Anxiety
Neurofeedback can also be beneficial for individuals suffering from depression and anxiety. By promoting self-regulation of brain activity, neurofeedback can help individuals gain better control over their emotional responses.
Managing Epilepsy Through Neurofeedback
Research has shown that neurofeedback can help manage epilepsy by training the brain to avoid patterns that lead to seizures.
General Cognitive Function and Mental Health Improvements
Beyond treating specific conditions, neurofeedback can also contribute to general cognitive function improvements and better mental health. By learning to control their brain activity, individuals can enhance their focus, reduce stress, and improve their mood.

Identifying Desirable Brain Wave Patterns
The first step in neurofeedback training is to identify desirable brain wave patterns. These patterns vary depending on the individual’s goals and the specific issues they want to address.
Guiding Brain Activity Toward These Patterns
Once the desirable patterns are identified, the individual is trained to guide their brain activity toward these patterns, using the feedback provided during the neurofeedback sessions.
The Concept of Self-Regulation of Brain Functions
At the heart of neurofeedback is the concept of self-regulation of brain functions. By gaining a better understanding of their brain activity, individuals can learn to control their brain waves, leading to improved mental performance and well-being.
Long-Term Changes and Neuroplasticity
With consistent training, neurofeedback can lead to long-term changes in how the brain functions. This is due to neuroplasticity—the brain’s ability to reorganize itself by forming new neural connections. Neurofeedback leverages this ability to help individuals make lasting improvements in their brain function.
