Ambulatory distance, time, episodes, resting time, latency toward center of the chamber, number of center zone entries, stereotypic counts, jump counts, and jump times were analyzed using activity chamber after 24 days of treatment with vehicle or P110 at 3 mg/kg/day in G93A SOD1 mice. n = 7 for WT mice; n = 7 for G93A ALS mice + TAT; n = 14 for G93A ALS mice + P110; probability by one‐way ANOVA (with uncorrected Fisher's LSD post hoc test). An experimenter who was blind to genotypes and drug groups conducted all the behavior and survival studies. Mean, standard deviation, and P‐values are shown.
