REPOST from Stanford Medicine:
If you’ve ever felt like your stomach has a mind of its own, there’s some truth to that gut feeling.
The human digestive system contains hundreds of millions of neurons — more than the entire spinal cord. This “second brain,” called the enteric nervous system, coordinates the movement and digestion of food and communicates with the rest of the body. Yet scientists still know surprisingly little about how it works.
Now, Stanford researchers Todd Coleman, PhD, and Julia Kaltschmidt, PhD, are creating detailed maps of this system to understand how its neurons control digestion and other essential processes — work that could help transform treatment for conditions ranging from irritable bowel syndrome to Parkinson’s disease.
