- Patrick Drew leads the Penn State team that reported the brain‑motion effect in a Nature Neuroscience paper on April 27, 2026.
- Penn State researchers used two‑photon microscopy and micro‑CT to image live mice, revealing that abdominal muscle tightening pushes blood through the vertebral venous plexus and nudges the brain.
- Abdominal muscle contraction creates a hydraulic pressure wave that moves cerebrospinal fluid across the brain, potentially clearing metabolic waste.
- Huck Institute of the Life Sciences is mentioned as Drew’s affiliate, highlighting the interdisciplinary engineering‑biology collaboration behind the discovery.
