Intro to The Data Science Behind EEG-Based Neurobiofeedback

The Neurobiofeedback machine gained popularity for its non-invasive and quantitative approach to behavior regulation, but its legitimacy remains in question by pediatricians, therapists, and other professionals. In academic-sounding terms, this machine (which I'll be abbreviating as NBF from now on) is built on the concept of feedback therapy, which exploits our ability to exert and/or regain control over physiological aspects in our body. NBF is a type of Brain-Computer Interface (BCI) machine that senses your brain wave activity in different ways (usually involving hardware-software interaction) and rewards you with an auditory or visual stimulus when your brain wave's frequency matches the desired frequency. This comes from the scientific notion that brain rhythms correspond to certain cognitive states. By "mind games", the'auditory or visual stimulus' I mentioned last paragraph usually comes in the form of a game.
