Neurofeedback is a type of Biofeedback.

Biofeedback is a treatment technique in which people are trained to improve their health by using signals from their own bodies and it is the only objective, self-directed, drug-free, and non-invasive method to control the involuntary nervous system by an individual.

The biofeedback unit is essentially a real time learning machine that, through visualized imagery, helps users gain access to some of the involuntary control systems of the body.

In any biofeedback system, there is generally a visual or auditory form of feedback, so that the trainee has an indication of what is going on. This display or sound provides an indication of the trainee's internal state, and it is through the awareness of that state that the individual learns.

The device used in the Brainscore performance is the BrainMaster2E.

The BrainMaster is a general-purpose brainwave monitor. It connects to a PC in the same way that a modem does; but instead of communicating over the telephone network, it monitors brainwaves.

Its capabilities include recording 1 or 2 channels of brainwaves or related signals, data storage and retrieval, real-time signal processing and display, plus various forms of control and feedback. It includes many graphical display modes. It is possible to interface with the software, so that various external programs can control the BrainMaster, as well as be controlled, enabling user-developed applications to interact with live brainwave data. Control and data interfaces to Visual Basic, Pascal, C, and C++ are provided.

With this device, you can digitally record, store, process, display, and work with brainwaves using any PC with Windows and a spare serial port. You will be able to monitor and display waveform characteristics such as alpha, beta, delta, or theta energy, the amount of symmetry in the brainwaves, or set up the system to respond to your brainwaves by creating displays, sounds, or other effects. This is useful for many applications in which there is a need to record and study brainwaves, to play games using brainwaves, or to use brainwaves to control a system, including interactive simulations and virtual reality displays.
