FIG. 2.

Sensory evoked potentials (SEPs). SEPs peak latency was measured from the start of the stimulus (A, arrow) to the first negative peak (N1). The evoked potential amplitudes were measured as the voltage difference from the peak of first positive peak (P1) to the peak of the negative peak (N1). Peak amplitude of SCI rats that received riluzole 1 and 3 h post-injury were 42.67±3.355 μV (p=0.004) and 37.00±4.555 μV, (p=0.046), respectively. Riluzole-treated rats had significantly higher peak amplitude than control (20.67±4.25 μV). The SEP latencies were not significantly different among groups.
