Neurofeedback

Neurofeedback is a specific form of biofeedback, providing feedback to the brain so that functioning can be optimized. Extensive research has shown that neurofeedback is an effective option for children and adults with difficulties such as concentration problems, hyperactivity, depression, anxiety and sleep disorders. It is a non-invasive method of training the brain to optimize the intricate interplay of brainwaves that determine our behaviour, emotions, thoughts and attention. The latest computer software provides the client with real-time, instantaneous visual and auditory feedback regarding what is happening in the brain. It enhances flexibility, thereby improving the brain's ability to respond with healthy patterns of functioning. Different speeds of brainwaves should be dominant when we sleep compared to when we need to focus on a complex maths problem. The goal of neurofeedback is to help an individual move from one brain state to another to accommodate each new task, therefore improving academic performance, mood, behaviour, and thought processing. Neurofeedback meets the criteria by the American Psychological Association to be classified as an evidence-based intervention.

 

Power Training

One of the earliest types of training that enhances a particular type of brainwave while simultaneously inhibiting brainwaves that are perceived to be preventing and individual from reaching optimal brain performance.

Alpha-Theta Training

Also one of the earlier training modalities, this is used to calm the brain and to assist with accessing deeper inner states leading to changes in awareness.

Coherence Training

This type of training can help different brain areas to efficiently connect with one another.

Live Z-score Training

This training provides continuous proportional feedback reflecting dynamic states of all Z-scores utilizing a normative database.

s-Loreta Training

This new form of training utilizes a mathematical equation where information from surface electrodes is used to observe and to train the internal brain structures.

ISF Training

Infra-Slow (ISF) Training is a recent development. It focusses on the lowest energy that the brain produces (<0.1Hz). Research indicates that it regulates autonomic functioning.

What happens in a Neurofeedback session?

               

Electrodes are placed on the client's head with paste to hold them in place and to conduct the electrical signal. One or two of these are also placed on the earlobe. These sensors measure the electrical activity coming from the brain at the specific sites being monitored. No electric current is passed into the brain. This information is fed into a computer for analysis and is converted into game-like displays on the client's screen. The better the client's performance, the more stimulating the feedback. The client is constantly fed information regarding the state of their brain with auditory and visual signals. After practicing this over a period of time, the changes are usually long lasting.
