Introduction to Neurofeedback?
Neurofeedback is a particular form of Biofeedback - in fact it is sometimes referred to as EEG Biofeedback which points to the fact that it relies on identifying EEG data (Electroencephalogram) from the brain. It's different from "conventional" EEG or so-called Quantitive EEG (qEEG) which are related areas of interest but are not the same as Neurofeedback and have a different intent. We don't go into great detail of Neurofeedback here which is beyond the scope of this note. However, the NeXus 4, NeXus 10 and NeXus 32 systems all provide an opportunity for the professional to explore this field.
Neurofeedback is based on sound scientific principles that have been around for more than 80 years of clinical and technical development. The idea is that we can identify particular "brain states" via looking in detail at the very small amounts of electrical activity emitted from the brain. We can typically detect this EEG information at the scalp. We can present this information back to a trainee in a number of ways so that they can learn to guide their brain to achieve and sustain new desirable states - whether these represent a return to "norm" or indeed a new level of performance.
Neurofeedback is not a "quick-cure" or a one-size-fits-all" type of the therapy (beware of anyone suggesting it is!). However, at it's root, neurofeedback embodies a process of neuronal self-regulation and re-education - the means to lead the brain to find new and beneficial states and ways of processing information and feelings.
Neurofeedback has already been applied in many situations including
- Traumatic Brain Injury
- Post-traumatic Stress Disorder (PTSD)
- Learning disorders and much more...
Key Elements of Neurofeedback
To tap into the potential of Neurofeedback you need access to excellent hardware and software. The NeXus range is ideal. The process is like this.
- the brain generates EEG as a natural process
- the EEG signals can be sensed by appropriate instrumentation (for example EEG cap with a NeXus 10 unit)
- the EEG signals can be digitised and captured for signal processing (BioTrace+ software)
- Feedback can be given to the trainee based on the processed state of the EEG (visual, auditory, tactile etc feedback) (BioTrace+ software). The dual-screen support offered by the Biotrace software means that the trainee doesn't see the complexity or detail of the EEG; they see a screen presentation that facilitates their training.
- The learning by the brain that results leads to physiological change
If you want the raw data for research purposes it's available without fuss. Whether you wish to deploy a "conventional" EEG Cap or the new EEG Headset (developed as part of a recent EU research study) we have the hardware and software you need.
