The more I learn about the human body, the more I am in awe of the heart. It is so much more than a pump or a rhythm that keeps us alive. Inside the heart lives its own network of neurons, tens of thousands of tiny nerve fibers woven through its tissue. Together they form what scientists call the intrinsic cardiac nervous system, often described as the heart’s little brain.
I first learned about this in a Visceral Manipulation class, and it changed the way I understood everything about the body. The idea that the heart could sense, respond, and regulate on its own opened something in me. I have always had a deep respect for the heart, especially after my thoracic surgery when my ribs had rotated toward my pericardium. That experience made me aware of how much protection and fragility live in the chest. But learning that the heart actually has its own neural intelligence brought that respect to a new level.
Science has shown that the heart can learn and adapt. These neurons communicate constantly with the brain and can adjust the rhythm and function of the heart in real time. What we do not yet know is whether this kind of adaptability could reach into emotional or experiential memory. The research is still emerging, but that does not mean it is impossible.
There are stories about the heart holding memory that stay with me. In one class, I heard about a young girl who had been killed, and the person who received her heart later recognized details that led to the discovery of her murderer. Whether that story can ever be proven or not, it speaks to something worth considering. There is still so much we do not understand about the intelligence of the body.
The structure of the heart itself adds another layer of wonder. The fibers are not arranged in straight lines but in spirals that twist and untwist with each beat, creating a continuous wave of motion. The heart does not simply contract. It flows, wrings, and releases, with strength and grace.
For me, curiosity lives in that space between what we know and what we feel. The heart’s neural network, its spiral architecture, and its constant conversation with the rest of the body all remind me that we are only beginning to understand how deep the connections truly go. I do not need every mystery to be solved to believe that the heart remembers something. Maybe not in words or images, but in rhythm, in resonance, and in presence.
Warmly,
Christine
