Neurofeedback is biofeedback for the brain. It is a technique to allow the brain to learn to control its own electrical activity, whether it is the alpha waves associated with calm, or the beta waves associated with focus. It can also help the brain strengthen its abilities, and to make new pathways to compensate for damaged ones. Cranial Electrical Stimulation is a pocket sized device that attaches to earlobe clips. It produces a waveform that demonstrably helps the cells of the brain go into an alpha wave (calming) mode. CES units can be used to lessen the anxiety associated with dental visits or therapy sessions. Microcurrent Electrical Therapy (MET), and Transcutaneous Electrical Nerve Stimulation (TENS) are therapies that have good data for enhancing tissue healing.
