AG: antonym generation task; VF: verbal fluency task; Similarity measure (r): spatial correlation coefficient between the CCOIs’ maps across both tasks; Temporal correlation with reference (r): correlation coefficient between CCOIs’ time courses and the reference function (mean ± STD across subjects), shown for CCOIs of each task separately in the last two columns. Activation regions and BAs of the language-specific CCOIs are listed separately for ag1, ag2, and vf1; those of the non-language-specific CCOIs are listed for both tasks together.
