eli5: What do our gut neurons do and how are they different from brain neurons?
gpt
We’re full of neurons all over. Gut neurons receive signals from and send signals to our guts. They network with each other, so signals can go from one part of gut to another and actions like peristalsis, or squeezing to move food through intestines, is coordinated. They can also send signals up tot he brain and down from the brain, which is how knowing we’re about to eat can make our stomachs secrete acid and anxiety can redirect blood from stomach to muscles for fight-or-flight.

Gut has more complex networking than most of our non-brain body, but we also have sensory neurons and motor neurons all over our bodies to receive sensory input and send orders to move.

Brain neurons have a lot of the central processing networks for things like processing vision, regulating hormones, coordinating movement, and of course thinking and feeling.
