It is a myth that we only use 10% of our brain but there are ways to improve the function of your 86 billion neurons. Neurofeedback can help people learn to modify their brain by displaying its electrical activity in real-time. By seeing and hearing the brain activity in milliseconds resolution, people can learn to modify a range of brain functions such as attention or arousal. Dr Duncan Banks of The Open University will give a presentation and live demonstration showing how brainwaves can be recorded from members of the audience.
