    Not magic, of course. It’s science.

    The elctrical activity in your brain is measurable by electrodes placed on your skull. What we then get is called an electro-encephalogram, short: EEG. Although they rather measure a summation of activity rather than individual neurons. Still, this allows to draw some conclusions and has been widely used in neuromedicine.
    For instance, it can help to diagnose epilepsy, or investigate sleep quality. In contexts of the Emotiv, to put it simply, it rather measures levels of concentration than actual thoughts.

    But, with sufficient training you can enable such a system to perform a bit more complex tasks, like opening or closing a mechanical hand, driving a wheelchair in a simple mamner, etc… Although, from my experience, the applications are very limited and unstable.

      What if, hear me out, there are a few people that can sense that activity when others can’t? Kind of like how some people see sounds and hear color. Since all of you all can’t really sense that shit, you are relentless against people who can. It’s interesting to me. I wonder how that first scientist figured this shit out. Do you know?
