Video 5
Fluid flow generated by wild-type ependymal cilia. Polystyrene beads were added to a vibratome section through the third ventricle and movements were recorded at 200 frames/s. For simulation of real-time movements, an average of eight consecutive frames was calculated in Video Savant and the average images were then displayed at 25 frames/s in QuickTime. See Fig. 7 for an analysis of bead movements.
