Your brainwave
Can you remember a
time in your life when everything was going well? You might have
been playing sport, playing an instrument, painting, studying or
working. You may have noticed that time seemed to fly past and you
had no worries, just an intense focus upon what you were doing.
When you achieve this
state, you have generally triggered a slower brain rhythm... the
alpha brain rhythm.
In the 1950’s Dr Jo
Kamier made a machine that showed the electrical output of the brain
- an electroencephalogram (EEG). He found that the brain produces
different levels of activity that can be measured on an EEG machine
– brain waves range from about 28 to 0.5 cycles per second (hertz).
The brain waves vary depending upon the state of cortical arousal
our brain is in.
The four major brain
rhythms are:
-
Beta,
-
Alpha,
-
Theta, and
-
Delta.
The brain rhythms are
summarised in the following table:

|
Beta |
Used by
adults the most. You are able to learn new information
which is stored in short term memory. The mind is
focussed on the physical senses, time, space, logic and
reason. In this state you can often be stressed. Beta
demands and uses large amounts of physical resources.

Alpha |
You are
relaxed and can retain information in your long-term
memory. The mind is intuitive, inspired and creative.
This level is known to aid in migraine/headache
alleviation. The Alpha and theta border helps to boost
the body’s immune functions. Neuro-chemical levels of
norepinephrine, serotonin and Beta-endorphins are
increased. |

Theta |
You are
very dreamy and it is hard to focus on things around
you. Most people fall asleep. The mind is unaware of
physical sensations. Control of functions such as the
heart beat and digestion occur here. We normally
experience theta only fleetingly as we rise up out of
the depths of delta upon waking, or drifting off to
sleep. We are in a waking dream. A brief period in Theta
(about 5 – 15 minutes) can restore the normal brain
ratio of sodium and potassium levels giving a feeling of
being mentally refreshed rather than mentally fatigued.

|
Delta |
This is
the level of the unconscious, deep sleep, coma and
anaesthesia. The only things that you can do are all the
basic movements controlled by the reptilian phase. The
mind is unaware of the physical plane. |
