Brainwave is the technical term for the electrical activity that is produced by the neurons in your brain as they communicate with each. It is described as a “wave” because it crests and troughs just like waves do.

Besides using brainwave apps and downloads, you can also use neurofeedback techniques to control your wave state. Neurofeedback technologies can include electroencephalographs (EEGs), galvanic skin response and heart, pulse and breath rate monitors.

Please refer to the book for more details on this activity.
