Neurofeedback
(also known as EEG Biofeedback)
is a method where you can exercise or "train" your brain
so that specific neuronal connections get stronger.

Goals in using neurofeedback include promoting a stable, flexible, and well-regulated brain.

This training:

inhibits excessive slow brain waves

inhibits excessive fast brain waves

rewards brain wave frequencies that contribute to a calm, relaxed, focused state.

In other words, neurofeedback is used to "wake up" a sleepy brain, "calm" an overaroused brain, and improve the timing and coordination of neuronal firing for peak performance training.
