Table 3.

Angles measured from slow motion recordings of ependymal cilia (refer to Figure 1).

	N	Mean Angle (°)	SD	SEM	+/_95% Confidence Intervals
L	106	12.1	4.5	0.4	0.9
R	106	12.6	5.1	0.5	1.0
Outer Left	106	85.6	13.4	1.3	2.6
Outer Right	106	69.8	11.8	1.15	2.3

OL: Outer Left: maximum movement of the cilium to the left with reference to the horizontal. OR: Outer Right: maximum movement of the cilium to the right with reference to the horizontal. L: maximum deviation of cilium left of midline. R: maximum deviation of cilium right of midline. N, number; SEM, standard error of the mean.
