- Data are given as mean ± SEM, with the numbers in parentheses indicating the number of FDB fibers tested. Conductance and charge movement data were fit by Eqs. 2 and 3, respectively. As in Table 1, the triple thin lines separate three distinct experimental groups: (1) symptomatic, (2) early-symptomatic, and (3) MLC/ SOD1G93A. Again, significant differences within each group are indicated (* denotes P < 0.05; *** denotes P < 0.001; unpaired t test)
