Strength of functional connectivity as a function of distance between groups. Mean Fisher z-transformed Pearson’s rho (ρz): for 3–4.5 mm: saline = 0.91, CI: 0.87–0.95; VPA = 0.82, CI: 0.77–0.88; p = 0.033; for 4.5–6 mm: saline = 0.81, CI: 0.78–0.85; VPA = 0.70, CI: 0.65–0.75; p = 0.003; both permutation tests.
