Time interval (min) | Bead displacement (μm)
|
---|---|
Average ± SD | |
9–14 | 1.51 ± 0.66 |
19–32 | −0.63 ± 0.46 |
63–101 | 0.83 ± 0.30 |
163–207 | 2.37 ± 1.22 |
Measurements were made on images in Figure 3. Positive bead displacement reflects centripetal movement of the beads towards the center of the visual field during the time interval of the experiment. Number of beads measured at each time = 14.
