For the first time, the Biofeedback magazine is dedicating a special issue to a living pioneer in the field of biofeedback and psychophysiology. Maurice Barry Sterman is currently facing significant health challenges, yet as of this writing he is still with us, continuing to contribute to neurofeedback and neuroscience.

This paper reviews and highlights the numerous contributions over more than 50 years of Dr. Maurice Barry Sterman. Sterman was one of the founders of our field of neurofeedback (neuroregulation). He was responsible for the development of the use of sensorimotor rhythm (SMR) training for the treatment of epileptic seizures. He has published widely and presented his findings worldwide. It has been a privilege to know him as a colleague and a friend for more than five decades.

This article shares personal reflections on the influence that Maurice Barry Sterman has had on the field of neurofeedback and on the personal lives and careers of two recruits to the field, a psychologist and a neurologist, both of whom pivoted from traditional careers to learn about applied psychophysiology. They comment on the scientific rigor of his work and, additionally, share personal anecdotes that give a glimpse of the man behind the science.

Disorders of gut-brain interaction, previously called functional gastrointestinal disorders, are prevalent, disabling, expensive, and difficult to treat. In this review, I trace the available scientific knowledge on the pathophysiology of these disorders and describe how the proposed pathways are integrated into treatment approaches. A novel treatment approach, heart rate variability biofeedback (HRVB), is described, and outcome literature is reviewed. It is concluded that an approach such as HRVB offers benefits beyond more traditional treatment approaches.
