A solution to the first step in creating the first brain computer interface (reliable detection of the electrical activity of the brain) was already on its way by 1929, when German neurologist Hans Berger recorded the first human electroencephalogram (EEG) (4). By placing external electrodes on the scalp of a 17-year-old surgical patient, Berger was able to measure the electrical potential across the electrodes and thus detect the changing electrical activity of the neurons in the patient’s brain. To this day, the EEG remains one of the most common methods of recording activity in the brain, favored over the MRI and PET scan for its cheap and relatively simple procedure. The next step, then, was to translate this recorded brain activity into meaningful information.
