[Polyvagal theory and emotional trauma]

Area of Science:

• Neuroscience
• Psychology

Context:

• Conventional autonomic nervous system theories are challenged.
• Polyvagal theory offers a new framework.

Purpose:

• To explain the hierarchical structure of the autonomic nervous system.
• To highlight the practical applications of polyvagal theory in trauma treatment.

Summary:

• The autonomic nervous system is divided into three hierarchical parts: primitive (vital functions), evolved (fight-or-flight), and most evolved (social involvement).
• Polyvagal theory has demonstrated efficacy in treating emotional trauma.
• In Finland, polyvagal theory integrates with structural dissociation theory for complex trauma therapy.

Impact:

• Provides a novel understanding of the autonomic nervous system's role in emotional regulation.
• Offers a therapeutic framework for complex trauma and emotional distress.
• Enhances psychotherapeutic approaches by integrating neurobiological insights.
