Neural Basis: Insula, ACC, and Connectivity Issues

Have you ever drawn a blank when asked how you're feeling? Or maybe you experience constant inner buzzing, numbness, or anxiety without any words to describe it. You’re not broken—and you’re not alone. In this deeply informative and compassionately nuanced episode, Jennifer, Elizabeth, and guest Matt Bush unpack alexithymia: a common and often misunderstood trauma-related trait that involves difficulty identifying, describing, or connecting with emotions.

More than emotional “numbness,” alexithymia involves disrupted communication between the body and brain, making healing feel elusive. The hosts break down the neurological roots of this trait, how it differs from emotional numbing in PTSD, and why traditional talk therapy often isn’t enough. You’ll learn how interoceptive training—like what's taught in NeuroSomatic Intelligence (NSI)—can help bring emotional awareness back online.

Whether you're a practitioner, trauma survivor, or someone just feeling disconnected, this conversation offers hope and concrete tools to rewire the nervous system for emotional clarity, embodiment, and relational healing.

Key Takeaways:

• Alexithymia is not a disorder but a trainable trait, often shaped by trauma and nervous system adaptations.

• Traditional talk therapy may not fully address alexithymia due to its neurological roots—interoceptive training is key.

• It differs from emotional numbing in PTSD; each involves distinct brain networks (e.g., DMN vs. salience network).

• Emotional awareness isn’t just about language—it starts with sensing the body.

• Healing emotional disconnect can improve not just mental health, but physical health and relational dynamics.
