What is Neurofeedback brain training?
Brain regulation & Neurofeedback
Our brains have their own regulatory system, which can be compared with a car’s automatic gear box – when working well it will automatically adjust the amount of power through the wheels according to circumstances.
In our brains, this “power” is blood flow. Highly intelligent people can quickly redirect blood flow to the right areas of their brains. Sometimes, this automatic control system doesn’t develop properly, or it gets disrupted by life events.
Our brains are amazing machines, the most complex structures in the universe. And it was discovered long ago that our brains will change in response to feedback. However because it is difficult to give the brain direct feedback, this feedback-based learning mechanism is rarely used. This means that when the brain’s regulatory system misfires altogether, causing mild to severe symptoms of conditions such as ADHD, ASD, depression or trauma, the lack of feedback means the brain doesn’t realise there is a problem. Just as it would be a struggle to drive a car without being able to see through the windscreen, or fly an aircraft without radar, without a correctly functioning feedback mechanism the brain’s control function can’t correct itself – it does not know how well it is working.
So in simple terms, Neurofeedback is a feedback tool to improve brain regulation. It closes the loop and provides high-quality information to your brain’s control function, allowing the brain to self-regulate and learn how to work better. The brain can adapt and improve its performance by using a feedback control function to self-regulate. And a bit like stabilisers on a bike, after some practice, we don’t need the stabilisers anymore.
Feedback systems are everywhere
This might seem strange until you consider how we use similar feedback tools daily.
Biology is full of feedback systems. In our bodies we have hundreds of feedback systems, for example, to regulate our temperature, heart rate or blood-sugar level.
Sometimes these feedback systems stop working properly or never develop properly in the first place. In some cases, we can use external feedback systems to correct things.
For example, a heart pacemaker measures the heart rate and fires an electrical pulse back to the heart if it detects a need for correction.
A blood sugar monitor detects when some insulin needs to be injected.
Neurofeedback is another external feedback system we use to get the brain working better. And its not just Neurofeedback practices like BrainTrainUK that use the ability of the brain to learn through brainwave feedback.
Neuroscience and Neurofeedback
In a 2016 study, neuro scientists described how they had used brainwave control and sensory feedback to teach paraplegics to learn how to walk using an Exoskeleton (bionic legs):
The neuro scientists created a feedback loop to the sense of touch so the brain could learn how to adjust brainwave activity to control the Exoskeleton. There was no ‘right’ way to do it, no ‘wrong’ way – it was just information. And they learned to walk!
This is exactly the same method of learning used by Neurofeedback, except we use 3 senses (sight, sound and touch) and instead of learning to control the Exoskeleton, the brain is learning to control itself.
How does the Neurofeedback technique work and is it safe?
Firstly, our treatments are completely safe. There is no surgery or medication, and the side effects are minimal and temporary. We measure brain activity by observing tiny electrical signals (brain waves). The technical name for this is electroencephalography or EEG, but it can be thought of simply as a kind of ‘stethoscope’ to see or listen to the brainwaves. Sophisticated computer technology assesses these raw brainwaves and that data is used to provide direct feedback to the brain on how it is functioning, using video software. Clients can watch videos, movies, documentaries or music videos. The picture changes in size, the volume changes to reflect your brain activity. A cuddly bear that vibrates can be used to give extra sensory feedback.
The good news is the client does not have to think, this all happens subconsciously – so the treatment works for very young children as well as adults. The client just relaxes and lets the brain use its own ability to self-regulate. Obtaining information directly from the brain and providing feedback straight back via the senses, in real time, is what makes Neurofeedback unique and so successful.
BrainTrainUK leads the UK in making this unique combination of technology and skills available in the UK.
