ABSTRACT
Electro-encephalograms (EEGs) are recordings of the minute (generally less than 300 mV) electrical potentials
produced by the brain. Since 1924, when Hans Berger reported the measurements of rhythmic electrical
activity on the human scalp, it has been suggested that these patterns of bioelectrical origin may provide clues
regarding the neuronal bases for specific behaviors and has offered great promise to reveal correlations
between pathological processes and the electrical activity of specific regions of the brain.
