Did you know that some scientists believe that a well functioning brain can generate as much as 10 watts of electrical power?
The electrical activity emanating from your brain is displayed in the form of brainwaves, which can be measured by an EEG.
I'm sure you have heard of biofeedback. Biofeedback is a way of gaining important information from your body in order to manage it better. Essentially, biofeedback is the science of self-regulation. For example, a simple form of biofeedback is using a thermometer to take your temperature.
Biofeedback is useful in treating many types of mental and physical problems. For instance EEG biofeedback (also called neurofeedback) uses an EEG, or electroencephalograph machine, to measure brainwaves - electrical vibrations from the surface of the scalp.
Because scientists have the ability to measure brainwave frequencies, it can now be determined how a person is feeling based on the brains neural activity.
Specific brainwave frequencies equal specific feelings – specific states of mind.
