The triune brain is a simplified model for thinking about survival and bodily regulation, emotion and attachment, and language and conscious thought. These functions involve closely connected networks. I find the model useful for noticing what our culture tends to overlook: we give language and thinking a great deal of attention, while feelings, sensations and impulses often go unnoticed. Working with the body brings them back into the picture.
This perspective may also matter when you live with chronic symptoms, particularly if diagnoses or treatments haven’t explained why the sense of alarm, exhaustion or pain persists.
