Abdominal Contractions May Drive Brain Fluid Flow, Aiding in Neural Waste Clearance
A new study in Nature Neuroscience shows that abdominal muscle contractions compress vessels linked to the spinal cord, nudging the brain within the skull. This subtle motion drives cerebrospinal fluid flow, helping to wash away neural waste. Researchers demonstrated the effect in mice using two‑photon microscopy, micro‑CT imaging, and computational fluid simulations. The findings provide a mechanistic link between everyday movement and brain health, suggesting a role for physical activity in preventing neurodegeneration.
