Solved cryptogram
Pain is made in the brain. The nerves report damage, and the feeling is built from that report.
Biology Facts, sourced to NCBI Bookshelf.
What it means
Specialized nerve endings detect heat, pressure or chemical signs of injury and send that information inward, but nothing about those signals hurts on the way. The brain weighs them against context, attention and expectation and generates the experience. That is why an injury can go unnoticed in an emergency, and why phantom limb pain is possible in a limb that is gone.
The claim comes from NCBI Bookshelf, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
