The study of emotion regulation has received a lot of interest over the past two decades and, with it, an increasingly sophisticated understanding of the neurobiological processes involved. The primary focus of this literature has been on explicit (i.e., deliberate) emotion regulation, and only recently has there been greater investigation of implicit (i.e., nonconscious) emotion regulation. It is the latter type that is therefore most relevant to an understanding of the neurobiology of the dynamic unconscious, as presented in psychoanalytic theories. In this commentary I summarize the state of knowledge regarding implicit emotion regulation, primarily focusing on experimental paradigms for which neural data have been reported. It is hoped that this perspective will augment Heather Berlin's article, covering other aspects of nonconscious processing relevant to the psychoanalytic concept of the dynamic unconscious.
