Test Banks With Solutions

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

who are the 2 most important pioneers in the field of EEG to know? 1. Richard Caton




• in 1875, recorded electrical phenomena on exposed cerebral hemispheres of rabbits & monkeys




2. Hans Berger




• in 1924, recorded 1st human EEG

• expanding on work previously conducted on animals by Richard Caton & others, also invented

electroencephalogram (giving the device its name)




describe the principle of EEG • scalp EEG reflects sum of electrical events throughout

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

resolution of ms
