EEG or Brainwave Neurofeedback

The EEG (or electroencephalogram) is an oscillating electrical voltage measured on the scalp. Computer analysis can reveal component rhythms within the EEG, sometimes known as brainwaves, which are associated with different styles of mental processing. For example:

• Delta rhythm is normally only present in deep sleep, but can be seen in some types of brain injury or depression cases.
• Alpha seems to be the brain's "idling rhythm", associated with relaxed awareness
• Theta is associated with an intuitive or dreamy processing style
• Beta is connected with awake thinking.

EEG is a complex phenomenon - these patterns are only loose correlations. How the EEG varies across the scalp, and the relative proportions of the rhythms, are significant factors. Read more in the article, 'Electroencephalography & Neurofeedback'.

How Does EEG Neurofeedback Work?

There is no single ideal brain state - rather, the goal is flexibility and balance. The brain needs to shift state easily to meet the needs of the situation - whether it's alert, focused thinking at work, or the suspense of a good thriller, or getting to sleep at night.

Neurofeedback seems to work by stimulating the brain to better regulate itself. It can help a wide range of nervous system problems.

York Biofeedback centre offers a form of EEG neurofeedback called Low Energy Neurofeedback System or LENS.
