Ultrasound Technique Boosts Brain’s Waste Disposal, Aiding Disease Research

Researchers developed a noninvasive, nonpharmaceutical method to enhance the glymphatic transport in the brain. The technique, known as focused ultrasound combined with circulating microbubbles (FUSMB), amplifies the effects of ultrasound waves on blood vessels, facilitating the removal of metabolic waste and distribution of nutrients.

Circadian Rhythms Help Guide Waste From Brain

During wakeful periods, the glymphatic system diverts cerebrospinal fluid to lymph nodes in the neck. The CSF may act as a "fluid clock" that helps initiate the body's infection-fighting capabilities during the day. Astrocytes in the suprachiasmatic nucleus may serve to control CSF through the central nervous system. Communication between astrocytes in different brain regions may optimize the glymphatic system's function as we sleep.
