Locating single neurons that monitor and regulate the heart and lungs

The body self-regulates in a process known as homeostasis, and the brain is responsible for this as it is constantly monitoring all of the body’s vital signals. If you need more oxygen, for example, then a message is sent to the brain that then tells the body to adjust your breathing and your heart rate. But the neurons involved in regulating breathing and cardiac rhythm had never been directly observed, until now, thanks to brain recording technology during brain surgery.
