Biological systems in the human body are constantly sending us messages.  We don’t usually pay attention to them until they become so loud we can’t avoid them (being startled, running up flight of stairs).  The internal messages are always there, but unless we exaggerate them or specifically look for them, they generally go unnoticed. 

When your doctor checks your pulse, he is listening in on biological information—hence, what he gets is biofeedback.  If your doctor uses a stethoscope to listen to your heart and lungs, he is using a simple biofeedback instrument. 

In recent years technology has allowed us to magnify the subtle internal body communications.  Quickly it was discovered that by getting feedback on internal processes, we could change internal activity.  We know that most of the body is communicating with other parts of the body.  We also know that we can now measure it.

In summary, biofeedback is a technique to achieve voluntary control of physiological functions which are normally regulated autonomously (e.g. heart rate, blood pressure, breathing).  Neurofeedback is the same process—a technique to achieve voluntary control of neurological functions. 

This is achieved through interactive games, each having multiple therapeutic applications.  These games, played by the client on a computer screen, provide variety of user experiences to condition the brain to work as desired.  The choice of game is based on several variables, including client age, assessment and preference.

As the client exercises the ability to voluntarily change brain activity, the signals are carried to the therapist station, where reward requirements can be adjusted and displayed back to the client screen.  This process is called “feedback” because it informs the client about his or her momentary success in making the desired brain changes.
