title: Alpha EEG asymmetry and speed of left hemisphere thinking.
abstract: Mental activity which engages one half of the brain is usually accompanied by a suppression of alpha rhythm that is greater over the active hemisphere. When the left hemisphere is active, as during mental arithmetic, the magnitude of the asymmetry in the alpha rhythm is proportional to the rate at which subjects perform their calculations.
