Variables obtained with fMRI and 1H MRS for each of the visual stimulation rates
| Rate | ΔBOLD, % | ΔCBV, % | ΔCBF, % | ΔCMRO2, % | ΔOEF, % | Δ[Lac], % | ΔJLac, % |
| 4 Hz | 1.8 ± 0.4 | 19.0 ± 4.6 | 51.7 ± 7.8 | 17.0 ± 3.3 | −22.7 ± 1.4 | 31.3 ± 4.4 | 7.8 ± 1.1 |
| 8 Hz | 2.5 ± 0.2 | 28.5 ± 3.8 | 65.1 ± 5.9 | 13.4 ± 4.0 | −31.2 ± 1.9 | 50.0 ± 5.7 | 12.5 ± 1.5 |
| 16 Hz | 2.3 ± 0.3 | 24.8 ± 5.1 | 57.2 ± 6.2 | 12.2 ± 4.1 | −28.9 ± 2.3 | 46.1 ± 4.7 | 11.5 ± 1.2 |
| F | 24.2*** | 24.3*** | 13.5** | 5.8* | 73.6**** | 25.8*** | 25.8*** |
| Post hoc | 4 << 8 = 16 | 4 << 8 = 16 | 4 << 8 = 16 | 4 < 8 = 16 | 4 << 8 = 16 | 4 << 8 = 16 | 4 << 8 = 16 |
Values are means ± SD. F values were computed by one-way, repeated measures ANOVA, ****P < 10−12, ***P < 10−6, **P < 0.001, *P < 0.01. Post-hoc testing was performed per condition by Newman-Keuls test, where << indicates P < 0.001, < indicates P < 0.01, and = indicates P > 0.5.
