Spotted: Brain “Clean-Up Crew”

While most biological systems use the lymphatic system to remove waste, the central nervous system uses something called the glymphatic system, which “cleans the cerebrospinal fluid (CSF) that surround the brain and spinal cord and relies on specialized CNS support cells known as glia.” Helene Benveniste at Stony Brook University used a fluorescent tracer in rats, and tracked it with an MRI scan. This study has identified “two key influx nodes” in the brain. The team was able to measure the rate at which the glymphatic system removed the fluorescent […]
