Somatic Biofeedback and the Quest for the Therapeutically Meaningful Signal
The discovery of the hierarchical organization of networks has helped us to understand better just how the brain prioritizes functions. One network in particular, the Default Mode Network (DMN), changes how we now look at self-regulation techniques, including neurofeedback. NFB has been shown to alter the DMN. Somatic biofeedback has been shown to alter the brain in a similar fashion. For example, Critchley et al. found profound changes on frontal and cingulate sites with biofeedback training to lower skin conductance.
