Figure 4

Sensory evoked potential (SEP) latencies demonstrated no significant difference between injured wild-type (n = 5) and injured IL-11Rα-deficient mice (n = 5). (A) Representative average waveforms are provided for injured and uninjured wild-type and IL-11Rα-deficient mice showing point of stimulation (S) and first positive peak (P1). (B) Both wild-type and knockout injured mice demonstrate significantly greater latencies compared to both uninjured wild-type (n = 4) and uninjured knockout (n = 4) control mice while uninjured wild-type and uninjured knockout mice do not demonstrate significant differences in latency from each other. Data represent mean ± SEM (error bars). *P <0.05 (one-way ANOVA followed by post hoc Bonferroni test).
