Neurofeedback is a type of biofeedback that uses electroencephalography or Functional MRI to provide a signal that can be used to receive feedback information about brain activity.
Like other forms of biofeedback, neurofeedback training (NFT) uses monitoring devices to provide moment-to-moment information to an individual on the state of their physiological functioning. The characteristic that distinguishes NFT from other biofeedback is a focus on the central nervous system and its relationship to the brain. NFT has its foundations in basic and applied neuroscience as well as data-based clinical practice. It takes into account behavioral, cognitive, and subjective aspects as well as brain activity.
