A and B show the distance travelled, C and D show the total movement time, and E and F show the time spent in the center of the open field, 30 and 90 days after exposure, for the soman-exposed rats who received only ATS (0.5 mg/kg) and HI-6 at 1 min after exposure (n = 13), similarly treated rats who received also LY293558 at 1 h after soman exposure (n = 11), and controls (n = 17). **p < 0.01 (ANOVA, Dunnett post-hoc test).
