Medicine has long assumed that memory resides solely in the brain. Yet, emerging science shows that the heart retains structural, electrophysiological, and autonomic patterns that shape how we experience, respond to, and encode life itself. "The Heart Has a Memory" explores the heart–brain continuum, bridging cardiology and neurology, and revealing how emotional, moral, and physiological experiences leave indelible traces within the heart. Drawing on developmental biology, neurocardiac research, and clinical insights, this book presents a new paradigm: understanding is distributed, embodied, and intimately connected to the rhythm of the heart. For clinicians, researchers, and intellectually curious readers, this work challenges conventional thought and opens a window into the intelligence of the heart.
