Catching those crazy brain waves
...What are brain waves?
They're oscillating electrical voltages in the
brain - very tiny - just a few millionths of a volt.
They're measured by an electroencephalograph, producing
what we see as an electroencephalogram (EEG).
The first brain wave to be discovered was the
Alpha wave, named such because it is the first letter of the
Greek alphabet. It was discovered in 1908 by an Austrian
psychiatrist named Hans Berger.
Scientists have broken down brain waves into
four groups:
- Beta: 13 cycles per second (or Hertz) to 100-plus
cps
The Beta brainwave pattern is that of normal waking
consciousness; it's associated with alertness, arousal,
concentration. For most people, most of the time, beta waves
are most prominent.
The higher-end Beta waves - 30 Hz and higher - are associated
with times of uneasiness, distress and anxiety. The extreme
high end is associated with the “fight or flight response.”
This pattern occurs soon after closing our eyes and
relaxing. Alpha brain waves are associated with introspection;
when Alpha waves are prominent, the body produces calming
neuro-chemicals.
The higher end is associated with a “super learning” state -
when you’re deeply absorbed in a book, for example.
Pre-sleep or pre-waking drowsiness are at the lower end of
the Alpha range. It’s associated with peace and contentment and
is the predominant brainwave pattern of traditional
meditation.
This is the pattern for REM (rapid-eye-movement) dreaming
sleep. It's associated with enhanced creativity, memory,
healing and where we put together previously disparate pieces
of information, leading to an “ah-ha” experience or sudden
understanding.
Many psychologists believe the Theta state is the doorway to
the unconscious mind.
Delta is the slowest pattern, that of dreamless sleep.
Carl Jung postulated that in the Delta brainwave pattern we
make contact with the “collective unconscious” shared by all
humans. A feeling of unity or oneness is experienced in
Delta.
It is possible to be alert in the Delta
brainwave state, as long as there is a small amount of Beta,
Alpha or Theta pattern present, as well.
It should be noted that we all create some combination of all
four categories of brain waves all the time. For most people,
most of the time, Beta waves, being that of wakefulness, are
most prominent.

What I've foundI've been interested in this topic for
quite a while. Over the past few years, I've come across some
great books and websites that will help to shed more light on
the subject.
Here are a few books I
can recommend.
On my nightstand, I have several CDs created for the purpose
of entraining the brain to specific brainwave patterns.
And if you'd like to venture through the beautiful
world of "now," I know of some excellent tools to take you
there ... of course, you're *always* there anyway ...
