Five samples each of the ventral and dorsal portions were used. The crush injury currents produced in the ventral portion of the spinal cords had a median value of 278.79 μA/cm2, a minimum value of 184.75 μA/cm2and a maximum value of almost 1.06 mA/cm2. Alternately, the crush injury currents produced on the dorsal portion of the spinal cords are almost 3 times lower, with a median value of 60.29 μA/cm2, minimum value of 32.23 μA/cm2 and a maximum value of 72.32 μA/cm2. Comparison of these data using a two-tailed Mann-Whitney non-parametric test revealed the differences between dorsal and ventral ionic current flow to be extremely significant (P = 0.0079). |
