While fNIRS measures the brain's oxygen levels to map out neurological activity, the problem was that patients' hair was blocking the signals. But this sophisticated brush, developed by researchers at the University of Texas at Dallas and the University of Texas at Arlington, sends the data all the more clearly thanks to increased scalp contact. So this brush is not really for beauty as much as it is for medical purposes, but it's still pretty mind-bending, no?

Get ready sci-fi aficionados, because scientists have recently developed a hairbrush that reads your mind. OK, so it literally doesn't know who you're crushing on or what you'd really like to say to the lady who always pushes in front of you on the subway. What it does do is oversee mental activity by using functional near infrared spectroscopy (fNIRS).
