Effects of tDCS of the DLPFC on brain networks: A hybrid brain modeling study
Fig 4
Difference in BOLD signal, flexibility, and complexity among three periods in left DLPFC-tDCS protocol (F3a-Fp2c).
(A) The correlation between changes in BOLD signal in whole-brain (excluding the anodically and cathodically stimulated regions) across three periods and the strength of their SC to the anodically stimulated region. Vertical axis: t-values from paired t-tests comparing BOLD signal differences between the stimulation period (During) versus baseline (Without) and recovery (Post) periods (During > Without and During > Post contrasts). Horizontal axis: the strength of SC between whole-brain and the anodically stimulated region. (B) The complexity and flexibility of the brain across three periods. Statistical comparisons of the Without-tDCS, During-stimulation, and Post-stimulation conditions were performed using paired sample t-test. Data are expressed as Mean ± SD. *: , **:
