Caption According to Michigan State University researchers, glass catfish that swim based on the Earth's magnetic field, could one day hold the key to how the human brain works and how diseases such as Parkinson's and other neurological disorders function. In this video, a magnet is activated, sending electromagnetic waves through a tank, and a small school of glass catfish immediately change their swim pattern.
