Effects of EOM Sal B and β-THP Sal B on spontaneous locomotor activity in rats. Rats were habituated in activity chambers for 30 min prior to vehicle (75% DMSO) and time-course and total locomotor activity counts evaluated following EOM Sal B at a dose of 0.1 mg/kg, i.p. (light blue) (a, c), and 0.3 mg/kg, i.p. (dark blue) (b. d) and β-THP Sal B (1.0 mg/kg, i.p.) (light green) (e, g), 2 mg/kg (dark green) (f, h). Values represent mean ± SEM (N=6-9)
