| Subgroup A | Subgroup B | Control group | F | P | |
|---|---|---|---|---|---|
| Lower dorsal ARAS | |||||
| FA | 0.68 (±0.12) a | 0.77 (±0.06) b | 0.81 (±0.02) b | 7.10 | < 0.05* |
| TV | 730.84 (±425.17) | 950.08 (±412.12) | 953.61 (±156.14) | 0.69 | 0.20 |
| Upper ARAS | |||||

Values represent mean (±standard deviation); ARAS Ascending reticular activating system, FA Fractional anisotropy, TV Tract volume; One-way ANOVA and the LSD post hoc test were used for comparison of diffusion tensor parameters
