Neurofeedback

Neurofeedback uses EEG to give the brain information about itself in real time and asks it to adjust. These adjustments act as “exercise” for the brain and over time teach the brain to function in healthier and more efficient ways. This non-invasive, drug free approach has been proven to enhance the brain’s ability to regulate itself and therefore improve the brain’s ability to function optimally. 

Connectivity Neurofeedback (or in some research, Multivariate Coherence Neurofeedback) is an advancement over traditional Neurofeedback in many ways. Rather than training in a 2-dimensional fashion, CNFB views the brain in 3-dimensional space and targets the neuronal networking system accordingly. Specific mathematical formulas allow us to train with four channels. This increases spatial acuity, improves temporal resolution, decreases error rate, and allows for more precision. Studies have found that fewer sessions are needed to improve power and coherence compared to standard NFB training. If you’d like to learn more, this article provides a more detailed description of how CNFB works and why it is more effective than standard NFB. 

HOW DOES NEUROFEEDBACK WORK?

When neurons fire they produce electrical signals that can be measured using EEG. Neurofeedback software captures these signals, deconstructs them, and reconstructs them in a way that capitalizes on the brain’s plasticity. 

The participant can choose to watch a movie or play a simple computer game. Their brain wave activity is measured in real time via small sensors placed on the head. The software then modulates the auditory and visual feedback in response to how the brain is operating. “Healthy” activity is rewarded while “unhealthy” activity causes an interruption in the movie or game. The brain seeks out these sights and sounds without the participant’s conscious effort and “conditions” it to produce the correct brain waves more often. Over time, this unconscious process makes changes in the default brain wave activity, decreasing symptoms and producing desired states of functioning. Training the brain with neurofeedback can result in dramatic and lasting improvement in a wide range of neuropsychological conditions.
