Is neurofeedback safe?
The neurofeedback computer detects the energy the brain is using to perform a task (usually a strategic video game), rapidly divides the complexity of the brain waves into narrow bands of energy, then plays therapist-selected frequencies back to the brain as unique audio tones. Nothing is done to the brain . . . except give it information on how it is performing the task. Because the decision to increase or decrease any performance frequency is made solely by the brain, the process is perfectly safe.
