Neurofeedback is a biofeedback method that either displays real-time EEG data, or reacts to real-time EEG data. This enables users to learn how to self-regulate their brains. Below is the standard neurofeedback loop,
- Users watch the screen
- The computer tracks the mental state
- The computer responds to the mental state (informing the user)
- The user responds
- Back to step #1

The difference being, it is possible to directly measure the users current mental state with neurofeedback. Thus, providing a quicker and easier way to improve ones mental state.
