The Structural Mastery of Human Affect: Neurobiological and Somatic Foundations of the Core Emotion Framework

The Core Emotion Framework (CEF) presents a structural‑constructivist model of human affect built on three neurobiologically grounded hubs—the Head, Heart, and Gut. This paper develops the conative foundations of the Gut hub by examining Boosting as the organism’s fundamental “will to live” and analyzing the pathological Boosting–Constricting fusion that produces emotional rigidity. Drawing on somatic psychology, affective neuroscience, and polyvagal theory, we synthesize existing evidence to articulate how this fusion creates a conditional “right to live” enforced through tonic bracing and high‑arousal paralysis. We clarify that CEF is a theoretical integration rather than an empirical claim, using these literatures to support a coherent structural model. Emotional agility is restored through two mechanisms: (1) balancing Boosting with Accepting in the pelvic core to counter chronic sympathetic contraction, and (2) relocating Constricting to the Heart hub, where it regulates relational aperture rather than survival‑level inhibition. We further describe how midline‑crossing protocols facilitate bilateral integration and enable the left‑right coordination required for affective regulation. This framework provides a reproducible blueprint for transitioning from rigidity to grounded agency and reclaiming an unconditional will to exist. The Core Emotion Framework organizes human affect into three neurobiologically grounded hubs—the Head (cognitive‑regulatory), Heart (relational‑affective), and Gut (conative‑existential)—each defined by a distinct set of operators whose interactions determine emotional agility or rigidity.
