Long History of Measurement of Brain Electrical Activity
Utilizing EEG Technology

  • EEG was first recorded in humans by the German physiologist and psychiatrist Hans Berger in 1924, whose hope it was that EEG would revolutionize diagnosis and treatment of neurological and psychiatric disorders.
  • It was not until decades later with the advent of computerized methods for signal processing of brain electrical signals that the clinical utility of EEG was advanced.
  • The clinical utility of EEG technology has particularly advanced in recent years given the convergence of:
    ̶ Advanced signal processing methods
    ̶ Leveraging of machine learning and “big data”
