Your heart has its own mini “brain”

The heart contains about 40,000 specialized neurons—often called the intrinsic cardiac nervous system.

This network can sense, process, and respond to information independently of the brain, helping regulate heart rhythm even when brain signals are disrupted. In rare cases, transplanted hearts have continued beating normally before being connected to the recipient’s nervous system.

Why it’s wild: Your heart isn’t just a pump—it’s a semi-autonomous decision-maker.
