What the body tells us

The heart’s own network

Nerve cells in the heart.The heart has its own web of many thousands of nerve cells, the intrinsic cardiac nervous system. Some call it the heart’s “little brain”.
Two-way traffic.The heart sends signals up to the brain as well as receiving them.
A wise caution.This does not mean the heart thinks or feels for us.
An echo.Yet it is a wonder that the heart, too, listens and speaks.

What is known, told plainly, and nothing more claimed.
