Bill Scott, a pioneer in using EEG to detect and transform brain waves into computer generated graphics, has a website full of spectacular imagery created by the technique. Though fascinating and indeed a curious phenomenon to us here, it is not clear what a physician might use this for in practice.
Here’s a snippet from Bill Scott’s site:
First of all, BrainPaint does what other systems do with regard to thresholding by rewarding and inhibiting specific brainwaves. It just does it automatically. It gives audio and visual representations of that same linear data. Additionally, BrainPaint extracts a new metric on the complexity of the EEG and feeds that back visually in a language the brain functions in. Our brains and BrainPaint are complex systems — BrainPaint takes information communicated directly from the brain and creates real-time fractal images that the brain appears to understand. Most EEG biofeedback systems only give information on the size and speed of brainwaves which the research suggests is plenty to enhance performance. Yet there are many studies, including those Bill was involved in, that failed to significantly change the faster frequencies even though nearly 80% of the subjects showed significant improvements in their change objectives. This suggests the brain is changing something in the nonlinear realms. Bill has discovered a new metric that BrainPaint records and gives feedback on as well. The additional feedback encoded in the fractal pictures could be the reason why BrainPaint is so effective.
