Quantitative analysis of the mean edge displacements in different cell pairs. (A) Statistics of the mean edge displacements of connected cell pairs. Cell pair, n = 31. (B) Statistics of the normalized displacements of the connected cell pairs. Cell pair, n = 31. (C) Normalized displacements of the connected cell pairs versus the modulation voltage. The dash line indicates ND=2. Cell pair, n=4. *p < 0.05, ***p < 0.001, two-sided Student’s t-test.
