P1, rs-fcMRI. Top: Average FC within each network over time, pre- /post- the initial, in-office tPBM series and the later, at-home series. Compared to pre-treatment, there was a pattern of increased SN FC at 1 week and 1 month, but not at 3 months. There was return of increased SN FC after 12 weeks of home treatment. Bottom: Significant correlations were present between increased SN FC over time, and Stroop, Trials 3 and 4 (D, E), CPT (F, G), and PTSD (H); and between increased CEN FC over time, and CVLT (I, J) and BDI (K). rs-fcMRI, resting-state functional-connectivity MRI; SN, salience network; CEN, central executive network; DMN, default mode network; CPT, computer-timed, Continuous Performance Test; CVLT, California Verbal Learning Test; BDI, Beck Depression Inventory.
