The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault. gyroscope is a device for measuring or maintaining orientation, based on the principles of angular momentum.[1] Mechanically, a gyroscope is a spinning wheel or disk in whic â¦ h the axle is free to assume any orientation.
Over the years the EEG electrodes, amplifiers, and output devices were improved. Scientists learned the best places to put the electrodes and how to diagnose conditions. They also discovered how to create electrical maps of the brain. In 1957, Walter developed a device called the toposcope. This machine used EEG activity to produce a map of the brain's surface. It had 22 cathode ray tubes that were connected to a pair of electrodes on the skull.
