TIL in 1991 it was discovered that the heart has its “little brain” or “intrinsic cardiac nervous system.” This “heart brain” is composed of approximately 40,000 neurons that are alike neurons in the brain, meaning that the heart has its own nervous system.

I feel like they are slowly going to discover this about all organs.

Yes, it helps regulate the heartbeat. Your stomach also has neural cells. They help regulate automatic digestive processes

The title (badly) re-words the same idea a couple of times, cementing the idea that what the title says is still true if stated another way. It also seems to redundantly express the same idea more than once redundantly, meaning the title could be considered redundant.
