Ciliary Beating Compartmentalizes Cerebrospinal Fluid Flow in the Brain and Regulates Ventricular Development

？ Spatially organized motile cilia with rotational beats create directional CSF flow ？ Ciliary beating, heartbeat, and locomotion generate distinct components of CSF flow ？ Joint action of these components balances CSF compartmentalization and dispersion ？ Disruption of ciliary beating leads to ventricular defects during brain developmen
