Fig. 6: Relationship between GWBPR, myelination, and sensorimotor-association axis.
From: Functional contrast across the gray-white matter boundary
a–c The cortical distributions of myelination, GWBPR, and the sensorimotor-association axis are shown across the brain. The color represents the metric value (blue = low, red = high). d A negative correlation (r(358) = −0.32, p = 2.2825e-09, 95% CI = [−0.42, −0.22]) is observed between GWBPR and myelin content. e A positive correlation (r(358) = 0.41, p = 5.9262e-15, 95% CI = [0.32, 0.50]) is found between the GWBPR and the sensorimotor-association axis. Each point in the scatterplot represents a brain region, and the fitted line depicts the general relationship between the two measured metrics. Two-sided Pearson correlation was used to assess the association between variables. GWBPR gray-white BOLD power ratio.
