Neurofeedback is training for the brain. Brainwave sensors are used to detect brain activity. The neurofeedback software reads your brainwaves and identifies “turbulence.” Then it feeds back information in the form of sound, which you hear through earbuds; it sounds like static. The brain unconsciously understands this information and uses it to self-correct, changing its activity to be within the optimal brain wave frequency. The result is a calming effect. Neurofeedback is a non-pharmaceutical therapy treatment with no known negative side effects. It can help with anxiety, stress, insomnia, depression, and ADHD. Neurofeedback training can also improve focus and concentration. Students, athletes, and business people often find it gives them an edge.
