Alpha (Mid)
10.00 Hz
10 Hz is in the middle of the alpha band of brain activity, as recorded by EEG (sensors on the scalp).
How well is this supported?
Measured directly, or defined by a published standard.
The band is a standard way of describing EEG recordings. Band edges are conventions, and what a person experiences varies. This is not medical information.
This is too slow or too fast to hear, so the button plays it moved by whole octaves. Start with the volume low.
About this number
10 Hz is in the middle of the alpha band of brain activity, as recorded by EEG (sensors on the scalp). A 2017 glossary from the International Federation of Clinical Neurophysiology (IFCN) puts alpha at 8 to 13 Hz. Band edges are conventions and vary by source. Alpha activity is prominent in relaxed wakefulness with the eyes closed.
What is said about it
What is said, not what was measured
Popular descriptions link this range to relaxed awareness, light meditation and an "optimal learning state".
History
Hans Berger made the first recording of human EEG in 1924 and published it in 1929.
