Mean (95% confidence intervals) readings of ependymal ciliary beat frequency using three different methods of measurement at two different temperatures
| Frequency (Hz) (95% confidence levels) | |||
|---|---|---|---|
| Temperature | HSV | Photomultiplier | Photodiode |
| 30°C | 27.7 (26.6 to 28.8) | 25.5 (24.4 to 26.6) | 20.8 (20.4 to 21.3) |
| 37°C | 36.4 (34 to 39.5) | 38.4 (36.8 to 39.9) | 18.8 (16.9 to 20.5) |
HSV and Photomultiplier n = 28 at 30°C and 37°C; photodiode n = 16 at 30°C and n = 23 at 37°C. HSV, high speed video.
