Fig. 2: Functional asymmetry maps.
From: Associations between fMRI signal amplitude, hemispheric asymmetry, and task performance
Vertex-wise asymmetry maps for 17 epochs of 7 fMRI tasks rendered on the left cortical hemisphere (a). The sample includes 989 healthy young adults. One-sample t test. P < 0.05, FDR-corrected for multiple comparisons. The radar chart (b) summarizes average asymmetry for each task epoch across 12 network partitions: Visual (VIS1 and VIS2), Somatomotor (SMM), Cingulo-Opercular (CON), Dorsal Attention (DAN), Language (LAN), Frontoparietal (FPN), Auditory (AUD), Default-Mode (DMN), Posterior (PMM), Ventral Multimodal (VMM), and Orbito-Affective (ORA) networks. Each spoke represents one of the 12 functional networks. For each network, the radial distance from the center reflects the average magnitude of asymmetry across all 17 task contrasts. Positive values (outward) indicate leftward asymmetry, and negative values (inward) indicate rightward asymmetry. Radar chart inner and outer limits are set at −0.3 and 0.3, respectively.
