Gamma brain waves have the highest frequency among all brain waves.
These waves repeat themselves, usually at intervals from 200-500 msec. The overall duration of lambda waves is roughly 100-250 msec. Lambda waves occur with saccadic eye movements during visual scanning, disappearing when eyes are closed and in sleep. Lambda waves are physiological, triangular shaped, sharp transients occurring over the occipital regions when eyes are open. 24 What do delta waves do to the brain? What do Lambda waves do?Ībstract.
