But the heart self regulates and if put in a solution of salt and potassium it will pump without input from a brain!

Muscles will do that. I don’t see this as a good argument for hearts being important

Just a neat thing imo

It is, but it’s more due to the fact that the heart is a muscle. It’s not like the heart is still alive in that state or anything.

Fair enough

Actually it’s not muscles. It’s a network of ganglia, neurotransmitters, protein and support cells, just like in our brain - aka the heart brain / intrinsic cardiac nervous system.

For example: we realize we are in danger. This is intuitive and sensed with the heart. As a reaction, the heart sends this to your brain, who can send signals to the body to make it ready for action / be alert.

The heart is a big part of your intuition, based on experience, while your brain is the more rational one.

If you’re ever interested in what they’ve researched so far, you should read this.

But wait, in the event of one sensing danger isn’t that triggered by stimuli picked up via the brain? It seems like the heart is the second step in this process.
