 eyeRythymsDescription,"When the eyes are closed, there is often a large increase in rhythmic brain activity in the range of 8-13 cycles per second (Hz). These alpha waves were one of the first discoveries that Hans Berger made with EEG. The ability to detect alpha waves when the eyes are closed varies greatly from person to person, however. Don\'t feel bad if you can\'t see them!","When the eyes are closed, there is often a large increase in rhythmic brain activity in the range of 8-13 cycles per second (Hz).

Estas ondas cerebrales, denominadas alfa, fueron uno de los primeros descubrimientos que Hans Berger hizo con EEG.
