A groundbreaking study from Oregon Health & Science University (OHSU) has, for the first time, confirmed the existence of a functioning glymphatic system in living humans — a theory central to the Perrin Technique!
Researchers recruited five volunteers undergoing neurosurgery between 2020-2023. During the procedure, the volunteers received an injection of a dye (gadolinium) into their cerebrospinal fluid, followed by MRI scans to trace the dye’s movement through the brain. The results, published on October 7, 2024, in the Proceedings of the National Academy of Sciences (PNAS), show cerebrospinal fluid flowing through perivascular spaces, detailing a waste-clearance network in the brain
This mapping of pathways that clear neurotoxins to the body’s lymphatic and venous systems offers powerful validation for Dr. Perrin’s approach to treating ME/CFS, Fibromyalgia, long COVID, and other conditions.
