Figure 3

Functional connectivity differences between unimodal and multimodal streams. Left panel: differences in cortical thickness, volume, mean functional connectivity (FC) with different smoothing parameters (Gaussian smoothing kernels: 5 mm, 4 mm, and 6 mm), median FC, and mean FC computed using a subcohort of participants acquired with the same MRI protocol. Regions were reordered according to t-values from the paired sample t-test cortical thickness analysis (left hemisphere). The left insula was the parcel with the highest t value (absolute value); the left anterior cingulate (ACC) was the parcel with the lowest t value (absolute value). Right panel: differences in mean FC between unimodal and multimodal streams projected to the Schaefer 100-parcel atlas. A significant difference was reported only for the left prefrontal cortex. T: threshold, S: Gaussian smoothing kernels.
