Table 3 Results of mixed model analysis to determine the association between high-gamma activity during the sentence judgement period and those during working memory maintenance/scanning operations. The level of significance was set at p-value at ≤ 0.005, invoking Bonferroni correction for multiple comparisons within 10 regions of interest. HG: high-gamma. WM: working memory.
