Scientists discover a hydraulic link between the abdomen and the brain

A recent study published in Nature Neuroscience suggests that the brain is more mechanically connected to the body than previously appreciated. Scientists found that abdominal muscle contractions compress blood vessels connected to the spine and brain, pushing fluid that gently moves the brain within the skull. This physical swaying provides evidence for how exercise might benefit brain health by washing away cellular waste. Scientists set out t…
