Interesting, but I am always a bit skeptical about new technology like this, especially EEG/neurofeedback technology. The reason is because the proponents of this technology (i.e., QEEG) tend to make all sorts of claims about it that can’t really be backed up.

I have a couple of comments to make (since this image was taken from the post on my blog, I figure I have an interest in this
One — the images have nothing to do with neurofeedback per se. They are a graphical mapping of the nonlinear activity of the brain as per data taken from EEG recordings. So there is no “claim” there, just the mathematics.
Second, I declare my bias as a neurofeedback practitioner, but not a QEEG user — there is virtually no area of applied clinical interventions that can consistently back up its claims without negative data being available. Many drugs are used off-label, there are contradictory findings for the most commonly prescribed (e.g., antidepressants don’t do better than placebo in meta-analyses), many medications do harm that is initially unreported or unstudied — hence, the many lawsuits. Other clinical areas lack strong evidence of their functional efficacy (e.g., chiropractic, most rehab disciplines, most (non-cognitive)psychological interventions).
Nor do most critics of neurofeedback actually bother to keep up with the emerging evidence to really know.
Me thinks there is a double standard being applied to an area with both clinical and controlled studies of functional change and a history of safety in application.
