Relationship Neuroscience

In the current chapter, we review the research on close relationships done via the methodologies of neuroscience – in short relationship neuroscience (RN). Much of the research we review focuses on attachment (child–parent or romantic) and sexuality. Nevertheless, we aim to cover RN broadly defined. We start by framing our topic and providing a few working definitions. We then cover the various relational (attachment, interdependence) and neuroscience (social baseline theory, and the Functional Neuroanatomical Model of Human Attachment) theories, methodologies (MRI, ERPs, and genetics), and types of relationships (familial relations, romantic, friendships, sexual relations, etc.) used or covered in this subfield. We explore both positive and negative aspects of close relationships. Finally, we reflect on the bidirectional link and contributions between relationship science and neuroscience and suggest potential implications for mental and physical health and policymaking. We also outline some remaining issues and future directions for RN.
