The
exact boundaries between ranges vary among definitions,
and there is no universally accepted standard
The dominant
frequency determines your current state. For example,
if your alpha waves dominate, you are in the alpha state
(this happens when you are relaxed but awake). However,
also other frequencies will be present, albeit with
smaller amplitudes. Gamma waves aren't usually your
dominant frequencies.
