what is the historical origin of the EEG? • in 1875, Richard Caton recorded electrical
phenomena on exposed cerebral hemispheres of rabbits & monkeys
• in 1890, Adolf Beck found spontaneous electrical activity of brain of rabbits & dogs that
included rhythmic oscillations altered by light → brain waves
• in 1912, Vladimir Vladimirovich Pravdich-Neminsky recorded 1st animal EEG & evoked
potential of dog
• in 1914, Napoleon Cybulski & Jelenska-Macieszyna photographed EEG recordings of
experimentally induced seizures
• in 1924, Hans Berger recorded 1st human EEG
- expanding on work previously conducted on animals by Richard Caton & others, Berger also
invented electroencephalogram (giving the device its name)
• in 1934, Fisher & Lowenback 1st demonstrated epileptiform spikes

head
- measure of gross electrical activity of brain characterized by its frequency & amplitude
• not truly brain imaging technique
- however, EEG can be used to ascertain particular states of consciousness w/ temporal
