Maximum Pearson spatial correlation coefficient values (a) and corresponding mean ratio values (b) from activation maps generated by ICA (solid line), sDL (dotted line), and averaged sDL (dashed line) for six RSNs defined by the reference pig RSN atlas (EX, CERE, VIS, SM, AUD, and DMN). AUD, auditory; CERE, cerebellar; DMN, default mode; EX, executive control; ICA, independent component analysis; sDL, sparse dictionary learning; SM, sensorimotor; VIS, visual.
