Best quote from Finding the Brain's Off Switch for Stress: The Zona Incerta
Stress isn't just an unfortunate glitch in your biology; it is a highly sophisticated system designed to mobilize your brain and body. Because it is built on hardwired biological circuits, it has a literal 'off switch' that you can learn to flip in real time.

Finding the Brain's Off Switch for Stress
Frequently Asked Questions
The brain's off switch for stress is located in a deep region called the zona incerta, or ZI. Within this area, a specific group of somatostatin-expressing neurons, known as ZISST neurons, act as regulators for how the body handles chronic stress. When these neurons are active, they produce an antidepressant-like effect that helps maintain resilience and prevents the brain from sliding into depression-like behaviors.
ZISST neurons serve as the gatekeepers of your resilience by regulating the brain's response to prolonged pressure. Neuroscience research indicates that as long as these somatostatin-expressing neurons remain active, an individual can better weather difficult circumstances. However, if these neurons go quiet, the brain becomes more susceptible to the negative biological impacts of chronic stress and associated mood shifts.
While the fight or flight response is often viewed as an outdated evolutionary glitch, modern brain biology reveals it is actually a sophisticated system designed to mobilize the body. The discovery of the zona incerta's role shows that stress is governed by hardwired biological circuits. This means stress isn't just something to endure like a weather pattern; it is a system with a literal switch that can be influenced in real time.
