In this grounded and intimate episode of The Observable Unknown, Dr. Juan Carlos Rey of crowscupboard.com explores the silent symphony within the chest - the electromagnetic rhythm that links body, brain, and emotion.
Neurophysiologist J. Andrew Armour of McGill University first described the heart’s intrinsic nervous system - tens of thousands of neurons that sense, process, and send information independently of the brain. Psychophysiologist Rollin McCraty at the HeartMath Institute revealed that the heart’s electromagnetic field extends several feet beyond the body and changes with emotional state. And neuroscientist Karl Pribram of Stanford and Georgetown suggested that perception operates holographically through waves of energy and interference.
Together, their work illuminates a profound insight: emotion is not merely felt - it radiates. Heart-brain coherence, measured through heart-rate variability and vagal signaling, aligns cognition and compassion. In moments of love, prayer, or shared song, human fields literally synchronize.
The heart is a resonant organ, a transmitter of empathy. Its rhythm communicates safety, trust, and presence faster than words. To “listen to your heart” is not merely metaphor - it is biology tuned to meaning.
The Observable Unknown continues its exploration of mind, matter, and mystery - returning from the quantum to the corporeal, from the photon to the pulse.
