Stephen W. Porges, PhD, teaches at the University of Illinois at Chicago. He is author of the 2011 Norton book The Polyvagal Theory.
Stephen Porges has been at the forefront of the investigation of the interplay between neurophysiological processes and developmental status.... It is with The Polyvagal Theory that Porges now presents, in a well-delineated and articulated volume, a highly testable set of hypotheses regarding how the human (and more broadly, mammalian) nervous system has evolved to promote affective regulation and social interaction.... I commend Porges on this effort. Substantial research across a significant career has been well considered and integrated into a quite engaging and stimulating model regarding the relationship between the heart and the brain.
