The insular cortex (or insula) is a region of the cerebral cortex folded deep within the lateral sulcus. It is the brain's primary center for interoception — the sense of the body's internal state.
Functions
- •Interoceptive awareness — sensing heartbeat, breath, gut signals
- •Emotional experience — translating body signals into felt emotions
- •Self-awareness — the neural basis of "I exist" experience
- •Empathy — understanding others' internal states through simulation
- •Decision-making — gut feelings that guide choices
Anterior vs. Posterior Insula
| Region | Function | ONDA Relevance | |--------|----------|---------------| | Posterior | Raw body signals | Level 1: Primary interoception | | Anterior | Emotional interpretation | Level 2: Emotional awareness |
In ONDA Life
The insula is the key target of Level 1 practices. By training interoceptive accuracy, you strengthen the insula's ability to provide clear, reliable signals about your internal state — the foundation of all self-regulation.
Scientific Basis
Built on: Polyvagal Theory (Porges); Psychoneuroimmunology (Ader & Cohen); neuroplasticity research.
