The Insula–Vagus–Skin Axis: A Proposed Neurobiological Integration Model for Autonomic Regulation
Abstract
The Insula–Vagus–Skin Axis (IVSA): The Amin Hypothesis This project establishes a new model for understanding how touch heals the nervous system. While we often think of skin as a "shield," the IVSA model shows it is actually a "portal" to the brain's internal monitoring system (the insula) and the body's calming system (the vagus nerve).
