The Brain’s Fluid-Filled Spaces During Growth
The human brain is not one solid mass. Buried within its gray and white matter are a series of four interconnected chambers, called ventricles, which produce cerebrospinal fluid. Abnormalities in the ventricles can give doctors an early warning that fetal brain development might be going awry. Researchers from Children's National Health System performed volumetric MRIs on the brains of healthy fetuses to assess how the ventricles, cerebrospinal fluid and the rest of the brain normally change over time.
