Neurofeedback is defined as a specialized field of biofeedback, dedicated to training people to control the electrophysiological processes of the human brain (Demos, 2005). It is a non-invasive technique that uses an electroencephalograph (EEG) to measure electrical brain signals in terms of frequency and amplitude, during a task performed by an individual. Once the EEG is recorded, the raw traces are then separated into individual frequency components (Delta, Theta, Alpha, Sensorimotor Rhythm and Beta), and the information about them is sent back to the individual, in real time, in a form which suits him. /she can consciously see changes in the electrical state of her brain. This process is called a neurofeedback loop because the person participating in neurofeedback training can see how the task they are performing changes their brain wave patterns. Participants are trained to increase or decrease the speed or size of brain waves in specific parts of the brain, and the changes are shown through audio, visual, or audio and visual feedback. According to Lake and Moss (2003), the public's search for neurofeedback training is growing; it gives the individual a more active role in their health care, it is non-invasive and it involves emphasis on the body and mind. Much research has been conducted in the field of neurofeedback to determine exactly how it can improve performance in certain aspects of daily human activity. For example, studies aimed at improving athlete performance have shown that neurofeedback can improve balance (Pop-Jordana & Demerdziera, 2010), aiming (Kerick et al., 2001), and concentration (Salazar et al. , 1990). It is also used to promote artistic performances...... middle of paper...... Gruzelier, JH (2003). The effect of training distinct neurofeedback protocols on aspects of cognitive performance.
