image: This is a scheme of the ventricles in the brain of mouse. The ventricular system consists of four interconnected cavities in which cerebrospinal fluid (CSF) is produced and transported. The inside of the ventricles is covered by a ciliated cell layer. Cilia are eyelash-like motile structures that protrude from the ventricular wall and through their whip-like beating action transport CSF within the ventricular system. Shown in yellow is the lower part of the third ventricle that is bounded by the two hypothalami, a region concerned with hunger, thirst, satiety, and day-night rhythms. This material relates to a paper that appeared in the July 8, 2016 issue of Science, published by AAAS. The paper, by R. Faubel at Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, and colleagues was titled, "Cilia-based flow network in the brain ventricles." view more
