Comparison of connectivity patterns with LASSO-GC and correlation measures.

Patterns are shown for one exemplary ROI pair from one subject. The t-scores from LASSO-GC analysis were z-normalized. Green dots represent voxels from right VP and red dots represent voxels from right FEF. A) Estimated connectivity patterns with the LASSO-GC measure. Significant t-scores are shown as arrows, with the thickness representing the absolute magnitude of the t-scores, and the color representing the sign of the t-score (orange for positive, blue for negative). B) Estimated connectivity patterns with the correlation measure. Significant cross-correlation coefficients are shown as lines, with the thickness representing the absolute magnitude and the color representing the sign (orange for positive, blue for negative). C) Summary statistics for the patterns shown in the previous two panels. For the correlation measure, FEF→VP and VP→FEF have the same summary scores since the measure is non-directional.
