Right Hemisphere Regulation designates the dominant role of the brain’s right cerebral hemisphere in the governance of autonomic, affective, and social-emotional processes — a convergence that depth-psychology literature treats as foundational rather than peripheral. Allan Schore’s developmental neurobiological corpus establishes this dominance most comprehensively, arguing that the early-maturing right hemisphere, with its dense orbitofrontal-subcortical interconnections, constitutes the hierarchical apex of affect regulation during critical periods of attachment. The right hemisphere’s privileged access to limbic and autonomic circuits makes it the substrate of what Schore calls ‘primitive emotional disorders’ and their repair in psychotherapy. Stephen Porges situates right-hemispheric dominance within polyvagal architecture, emphasizing that autonomic asymmetry places the right cortex in superordinate control of vagal tone, facial expressivity, and visceral emotion states. Daniel Siegel extends the framework to interhemispheric integration, arguing that the right hemisphere’s synthetic, body-integrating processing mode undergirds mindsight and interpersonal attunement, while its dysregulation underlies insecure attachment patterns. Iain McGilchrist, from a broader philosophical vantage, frames right-hemisphere orbitofrontal function as essential to emotional understanding and contextual regulation. A generative tension runs through the corpus: whether right-hemisphere regulation is primarily a neurobiological given or an experience-dependent achievement shaped by early relational environment — a question that carries direct clinical stakes.
