Locomotor activity during experimental protocols (see Fig. 1) in three pharmacological conditions: DMSO and 100 and 200 mg/kg modafinil. Five minutes were allocated in each gas change protocol (e.g., Baseline1, Baseline2, 10% O2). Significant differences among the three pharmacological conditions (F(2, 16) = 9.53, P < 0.01) and the four air conditions (F(3, 24) = 7.50, ε GG = 0.57, P < 0.01) were revealed by the two-way repeated measures ANOVA. However, interaction was not significant (F(6, 48) = 1.20, P > 0.05). DMSO: dimethyl sulfoxide. Baseline: room air condition, Recovery: room air condition
