Certain forms of neurofeedback are targetted at the default mode network. The Default-mode-network is a group of brain regions that is associated with self-referential thought. There have been reports of neurofeedback practitioners who have experienced improved novelty detection, higher emotional range, more flexibility of thought, and a greater balance between narrative and experiential consciousness. Certain neurofeedback protocols that target the Default-Mode-Network focus on the epsilon, alpha, theta, and gamma frequency bands. Synchrony in all those frequency bands has been argued to be a neural signature for awareness.
