Engaging core muscles—through movement, exercise or even coughing—may be a key regulator of blood flow in the brain. When the body moves, the contraction of abdominal muscles increases pressure in blood vessels connected to the brain through the spinal column. A new study by researchers at Penn State shows that the increased pressure creates ultrafast constrictions of major veins in the brain, momentarily increasing blood flow.
Understanding how the regulation of blood flow in the brain is influenced by movement in the body could help explain the connection between exercise and brain health or why migraines and headaches can become more severe with movement, according to the research team.
The paper describing the research, which was conducted in mice, appears this week in t...
