Neuroguide

What is Neuroguide?

Neuroguide is a 19 channel full cap EEG acquisition, analysis and Neurofeedback training tool developed by Dr Robert W Thatcher of Applied Neuroscience. We primarily use Neuroguide for our initial QEEG or Brain Mapping process. This is an electrical measurement, analysis and quantification of brainwave activity.

Collecting, Analysing and Comparing Data

The first stage is to gather and examine the raw EEG data using the cap which has electrodes embedded. The gel injected into the electrodes enables us to measure the electrical potentials generated by the brain and transmitted through the skull. These raw ‘squiggles’ can provide us with a lot of information about the brain, but by putting this information through the Neuroguide analysis software – a series of digitized filters – it provides a much clearer, visual and reproduceable picture of this brain activity. An individual’s data is then compared against a normative database which is a database EEG’s of healthy, high performing individuals of the same age as the client. This gives us a comparison of the client’s brain relative to a brain which is functioning optimally. We are able to look at the brainwaves in the respective bandwidths Delta (0-4 Hz), Theta (5-8 Hz), Alpha (9-12 Hz), Low Beta (13-16 Hz), Mid Beta (17-25Hz), Hi Beta (26-40Hz), and Gamma (41-70Hz). It also gives us information about the relationship of the brainwaves to one another, the symmetry of the brain, and the areas of the brain where deviation from normal may be manifesting itself as problematic symptoms and behaviours.

The data is also analysed in swLoreta – a complex mathematical calculation to identify the deep source of the electrical activity we are measuring on the scalp. This helps us to ‘GPS’ specific areas of dysregulation more accurately and give us a more detailed view of an individual’s brain function.

Profiling Symptoms

The QEEG maps are often useful to help facilitate an individual to understand their symptomatic and functional difficulties, emotions and behaviours.

The Neuroguide platform can also be used to undertake 19 channel ‘full cap’ LORETA  Z-score Neurofeedback training which correlates a client’s symptom’s with identified areas of dysregulation in the brain areas and brain Networks. When brain activity (amplitude or connectivity) changes in the direction desired by the customized neurofeedback protocol, a positive “reward” feedback is given to the individual. The ultimate aim of all Neurofeedback methods is to train brain waves to create conditioned self-regulation.

Training

This may be our preferred option on occasions, but requires application of the full cap for every training session which can be too difficult, especially for younger or more sensitive clients. We more commonly start with training Slow Cortical Potentials in the Infra Low modality to promote physiological self-regulation, stability and flexibility of the brain or Neurostimulation techniques to guide the brain gently into a better state of function.

We also have the option to move to Neuroguide training if we feel it appropriate at any point. There are many approaches to Neurofeedback training modalities – it is not that one size fits all – which is why we operate a range of modalities.
