Electroencephalography (EEG) is a study of changing electrical
potential of the brain. The apparatus used to measure this
electric potential of the brain is called electroencephalograph,
and the tracing or the printout of the measured brainwave forms
is electroencephalogram. Frequency is the number of complete
repetitive waves that occur in a given unit of time. Frequency
is measured in Hertz (Hz) or cycles per second (cps). According
to their frequency brainwaves are divided into 4 main groups,
also referred to as "brain states" EEG Brainwave Sample State of
Consciousness |Fully Awake and Alert Generally associated with
left-brain thinking activity - conscious mind| 8 - 13 cps
|Relaxed, Daydreaming Generally associated with right-brain
thinking activity - subconscious mind - a key state for
"relaxation"| |Deeply Relaxed, Dreaming Generally associated
with right-brain thinking activity - deeper subconscious to
superconscious Access to insights, bursts of creative ideas - a
key state for "reality creation" thr
