Dr. Tierney unpacks the emerging paradigm of network neuroscience and how our brain’s default mode, salience, and task networks interact with trauma, attention, and healing.

Dr. Tierney is a somatic psychologist, neuroscience and psychopharmacology professor, and psychotherapist with a passion for integrative healing. Specializing in trauma resolution, couples therapy, and somatic experiencing, he blends cutting-edge science with ancient practices to create transformative healing experiences. He is the host of the Boundless Body podcast and the author of the upcoming book Visionary Somatics.

Highlights:

  • What is network neuroscience?
  • How trauma disrupts brain network coordination
  • Understanding the salience, default mode, and task networks
  • Why somatic healing involves connective tissue, not just cognition
  • The dangers of spiritual bypassing through “idealized embodiment”
  • “Character armoring” and body-held trauma patterns
  • How imagination serves as a ground for healing
  • The death–rebirth archetype in psychedelic experiences
  • Transcendence vs. transformation in modern healing culture
  • Why safety and grounding are non-negotiable for deep work
