The Nervous System Map

Map the four-layer neurobiology model onto your loved one's specific history and presentation.

Week 2
Appendix B

The Four Layers

Layer 1 — Sensitivity: What signs of high sensitivity have you always noticed in your loved one? (Before the diagnosis, before the crises)
Layer 2 — Environment: What do you know about their early caregiving environment? (You don't need details — just general patterns)
Layer 3 — Identity: How does identity instability show up? (Changing values, relationships, sense of self)
Layer 4 — Reactivity: What does emotional flooding look like in your loved one? What triggers it?
