During a neurosurgical procedure in 1971, John E. Upledger observed a phenomenon that conventional medicine could not explain: the dura mater was pulsing rhythmically, independently of respiration and heartbeat. From that moment, a line of research was born—one destined to leave a lasting mark on the history of osteopathy. Upledger didn’t just observe; he measured, studied, and developed a clinical method and a school of thought that would bring the concept of CranioSacral Therapy to the world.

In this episode of “Impossible Interviews”, we enter the study of the physician who turned a subtle perception into a therapeutic model. With just five grams of pressure and deep listening, he combined anatomy, perception, cerebrospinal fluid, and emotional states. His insights—welcomed by some and met with skepticism by others—opened a new dialogue between medicine, neuroscience, and manual therapy.

An opportunity to reflect on science and method, intuition and verification, listening and transformation.
Because the body, when truly listened to, always has something to say.
