Rewiring and exercising brainwaves? It’s possible with neurofeedback therapy.
Neurofeedback therapy has been described as a method of rewiring and exercising brainwaves to stimulate normal cognitive brain activity. It is a method through which the brain is strengthened, exercised and calmed, and creates the possibility to improve stability.All about the brain
What is neurofeedback therapy?
- Normally the brain develops by being exposed to new stimuli.
- If the wiring in the brain is defective the new stimuli can cause disorganization.
- Brain cells do not die but shut down in order to protect themselves.
- With stimulation, increased oxygen and blood flow braincells could be brought back 'online'.
Neurofeedback therapy is non-invasive and assists children with learning difficulties
, ADD, ADHD and various concentration and focus related issues.
Similarly, the term biofeedback is used as it trains subjects to alter their own brainwave activity, blood pressure, muscle tension, heart rate, and other physiological responses previously thought to be beyond our control.
Biofeedback works on the notion that we have the innate ability to influence the automatic functioning of our bodies. It also uses operant conditioning to train individuals to improve their lives.
Explaining the EEG
Using the EEG (electroencephalograph) to measure brainwaves, functioning can be measured with greater sensitivity and accuracy. The brain emits many electrical signals of various frequencies. It is currently used in treating anxiety, insomniacs and epilepsy sufferers and many other disorders.
The brainwaves measured by the EEG are:
Nura experiences neurofeedback therapyNura's brain
- Delta 0.5-3Hz (deep sleep)
- Low Theta 3-5Hz (Tuned out, sleepy)
- High Theta 6-7Hz (creative, not focused)
- Low Alpha 8-10Hz (calm relaxation)
- High Alpha 11-13Hz (readiness state)
- SMR 13-15Hz (alertness and focus)
- Beta 16-20Hz (problem solving)
wiring is literally 'haywire'. We don’t know if areas in her brain that have shut down can be recharged, rewired and restimulated.
This therapy is non-invasive as the sensors are attached to her ears and visual cortex, one area we are working on at present, and the electrical signals are translated into a form she can detect - the music sequence. Nura can alter her involuntary responses by being 'fed back' information either visually or audibly.
When Nura meets the requirements we set for her in the therapy programme on the computer, then the music plays and the screen moves.
However, when Nura does not meet the requirements then the music and the screen stops playing. When this happens Nura realizes that her brainwaves are outside the limits set for her and she must focus on bringing them back within the limits set for her.
Our goal is to bring down Nura's Theta waves and increase her SMR which will allow her to focus on one thing for long enough for it to have meaning.
