Sweeping the Mind: The Microscopic Engine of the Ependymal Cells

The human brain is an incredibly high-performance engine, and like all engines, it constantly generates toxic metabolic waste. If this cellular garbage builds up, it causes catastrophic neurodegeneration. To prevent the brain from literally poisoning itself, it relies on a highly specialized group of microscopic janitors: the Ependymal Cells. Lining the deep, cavernous ventricles of the brain, t...
