What is EEG
biofeedback?
Attaching
sensors to different parts of the body allows electrical signals to be
detected: heart waves are called EKGs, brainwaves are called EEGs. These
signals carry important data about the condition and states of these two organs,
which in turn can be fed back to them resulting in improved functionality.
The
bioelectrical profile of the EEG is composed of information on thought,
metabolic state, hormonal state, attention, feelings and emotions. With the use
of neurotransmitters, brainwaves communicate with our body to direct movement,
sleep, thought, attention, etc.
Sometimes
our brain gets into inappropriate states and it doesn’t direct our emotions or
actions efficiently. This may result in ADHD, seizures, sleep disorders, depression,
learning disabilities, etc. EEG biofeedback is a way to train the brain to be
more efficient and effective – to be in the right gear for the task at hand.
We
are constantly receiving feedback from our world, then we learn and adapt
accordingly. This is the predominant way that we are taught new behaviors and
EEG biofeedback works in the same way. Great examples of feedback loops
include:
1.
A mirror gives you visual feedback on the state of your
appearance and inspires action. Behavior changes will be directly related to
the area of focus - you may get a haircut, change your stained shirt, get your
pants hemmed, brush your teeth or go on a diet.
2.
Video recordings give golfers and tennis players visual feedback
to fine tune their strokes and techniques.
3.
An audience gives a performer audible feedback on whether their
material is funny.
4.
Gravity gives you kinesthetic feedback on developing and
maintaining a state of balance on a bicycle.
In
the case of EEG biofeedback, software gives you visual and audio feedback on
states of emotion and cognition that are extracted from your EEG. Your brain
then learns to improve the management of these states.
Once
these new developmental skills are learned they eventually become automatic.
Just as you always remember how to ride a bike, improvements made with EEG
biofeedback you usually keep.
Specifically related to the needs of eating disorder
clients, neurofeedback is effective in treating sleep disturbances, depression
and anxiety without the need for medications. Often neurofeedback sessions are covered by insurance.
