Neurofeedback: a paradigm-shift in how we treat brain disorders? 

Neuroscience research has recently shown that cognitive training and meditation are able to induce plastic changes in brain function. But, what if the reverse was also possible: to directly train neural activity in order to alter cognition?

Thanks to novel technologies, humans can learn to self-regulate brain activity using a brain-computer interface, through a so-called "closed feedback loop", which provides instantanous information about the current state of the brain. Neurofeedback typically consists of a computer that records neural oscillations ("brainwaves") with non-invasive electrodes on the scalp, known as an EEG. Brain activity is then processed in real-time and represented visually to the user (i.e. fed-back) on a computer screen, for example through a video game.
