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.

owing to the asymmetry of the peripheral autonomic organs and the medullary control of the autonomic nervous system, the right side of the brain is always dominant in the regulation of autonomic function and, thus, emotion.
Porges establishes that right-hemisphere dominance in autonomic and emotional regulation is a structural neurophysiological given, not a contingent finding, grounded in medullary asymmetry.

the early maturing … right cortical hemisphere, moreso than the left, is particularly well reciprocally connected with limbic and subcortical regions … and is dominant for the processing, expression, and regulation of emotional information.
Schore identifies the early-maturing right hemisphere's privileged subcortical connectivity as the neurobiological basis for its dominance in processing, expressing, and regulating emotion.

The frontal pole is larger in the human right hemisphere … this hemisphere specializes in the processing of social-emotional information … and maintain controls over the autonomic … and endocrinological … activities that underlie emotional functions.
Schore documents the anatomical and functional basis of right-hemisphere specialization, linking orbitofrontal dominance to control of autonomic and endocrine systems underlying emotional life.

the treatment of impaired right brain affect regulation calls for a greater focus on the powerful nonverbal influences on the communications of primitive affects in the psychotherapeutic relationship.
Schore draws a direct clinical implication: repairing deficits in right-hemisphere affect regulation requires a nonverbal, right-to-right hemisphere therapeutic interface rather than verbal-interpretive technique.

Critical period dyadic experiences … are imprinted into and influence the phenotypic maturation of the various brain systems that set the limits and ranges of the types of external and internal information the child's emotion regulating right hemisphere can process.
Schore argues that early relational experiences epigenetically determine the functional capacity of the right hemisphere as an affect-regulating organ, establishing the experiential constitution of right-hemisphere regulation.
Schore, Allan N., Affect Regulation and the Origin of the Self: The Neurobiology of Emotional Development, 1994thesis
even the regulation of the body's autonomic nervous system, as well as awareness of one's own inner state … the whole body is represented in an integrated way in the right hemisphere.
Siegel synthesizes neurological evidence to show that the right hemisphere's integrative representation of the body underlies its dominant role in autonomic regulation and interoceptive self-awareness.
Siegel, Daniel J., The Developing Mind: How Relationships and the Brain Interact to Shape Who We Are, 2020thesis
Part of the right frontal pole of the brain, the so-called orbitofrontal cortex of the right hemisphere, is essential to emotional understanding and regulation. It is also where the emotional significance of events is consciously appreciated.
McGilchrist identifies the right orbitofrontal cortex as the essential neural substrate for both emotional regulation and the conscious appreciation of emotional significance.
McGilchrist, Iain, The Master and His Emissary: The Divided Brain and the Making of the Western World, 2009thesis
the unique role of the early maturing right hemisphere in affective processes and in the regulation of internal states.
Schore's foundational formulation positions the early-maturing right hemisphere and its orbitofrontal apex as the primary regulatory system for internal states across the lifespan.

This allows for pre-frontal (especially right) hemispheric regulation of the hypothalamico-pituitary-adrenocortical … and the sympathoadrenomedullary systems.
Schore specifies the right prefrontal-orbital pathway by which cortical regulation descends to govern the two major neuroendocrine stress axes, giving right-hemisphere regulation a concrete neuroanatomical mechanism.

The maturation of the prefrontal regions of the right hemisphere in early infancy allows for the development of right cortical inhibitory control over subcortical facial displays … a prerequisite of the adaptive expression of emotion.
Schore traces the developmental ontogeny of right-hemisphere regulation, showing how maturational progression of right prefrontal regions enables inhibitory control over subcortical emotional displays.
