Table 2.

The effective diffusion coefficients in the time scale between 16 and 32 ms (D ^eff _16–32ms) of single individual PrP and Thy1 trajectories. The difference between 1-wk vs. 2-wk neurons was statistically insignificant for both PrP and Thy1 (using the Mann-Whitney U-test), and therefore, the results are combined at the bottom of this table. The difference between CHO-K1 vs. 1 + 2-wk neurons in D ^eff _16–32ms was statistically significant for PrP (P < 0.001), but not for Thy1 (P = 0.93). P values in the table are for comparing PrP and Thy1 in the same cell type, and show the results of the Mann-Whitney U-test
