From this article:
"Being an academic neuroscientist, I didn’t limit my research to the
Google perspective, let’s call it. I leveraged an advantage that few
consumers have—access to peer-reviewed research and the training to
critically interpret it. [...] With help from colleagues, I sifted through thousands of academic papers that investigated neurofeedback. Our main finding?
At the time of our research, only nine neurofeedback studies had used
an adequate control group and a double-blind design (where neither the
experimenters nor the participants know who receives the real
treatment). Many of the studies showed that neurofeedback could improve
some behaviors, but no more than if participants underwent the same
procedure and received false feedback pre-recorded from another
participant. Changes in behavior relied purely on placebo effects."
"Since then, researchers have conducted two of the most rigorous
neurofeedback experiments to date. They showed that neurofeedback can
both substantially improve attention and also make us think we sleep better,
but not actually improve our sleep. Again, false feedback worked just
as well as real feedback. In other words, it doesn’t matter if you watch
your own brain, or if you watch a recording of Jim’s brain from last
week, you’ll improve all the same. The benefits seem to stem from being
highly motivated and exerting effort, rather than from altering
brainwaves."
