Fig 2.

A patient with a right medial frontal low-grade glioma (case 18 in Table 1). Activity estimates from right (A) and left (B) hand movements by using tb-fMRI (P < .05, family-wise error–corrected at the voxel level) are shown and are compared with the motor IC of rs-fMRI (C, z ≥ 2). The overlap between rs-and tb-fMRI results is illustrated in D, where spatial maps of B and C are superimposed after binarization and segmentation of the motor clusters (see “Materials and Methods”): 1 (light gray) and 3 (black), respectively, indicate rs- and tb-spatial maps, and their intersection is labeled 2 (dark gray). The concurrent ratio is 92% for this patient.
