2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
I actually arrived at this supposedly old idea on my own when I was reading about the incredibly complex enteric nervous system in med school. For some reason it struck me that the brain of my gastrointestinal system might be conscious. But then thinking about it further it didn't seem very consistent that only certain bigger neural networks that are confined by arbitrary anatomical boundaries would be conscious, so I proceeded a bit further from there.
