DEEP DIVE · CHAPTER 11
The Vomit Trigger
Dopamine can make you vomit. It triggers nausea at a small area of the brain that checks the blood for poison.
The same molecule that makes you want dinner can make you give it back, and the two jobs happen a few millimeters apart. I want to show you the one spot where your brain samples your blood on purpose, and decides you have been poisoned. Then I want to show you the three nausea habits I was taught that the trials never supported.
