8.00 Hz

8 Hz is the lower edge of the alpha band of brain activity, as recorded by EEG (sensors on the scalp).

How well is this supported?

MeasuredEEG band

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

8 Hz is the lower edge 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.
