Linear regression of the memory capacity and coherence for the four main regions of interest. “Control Variables” refer to the control variables of column 6 in Table 1. Columns 1–2 show a “horse race” regression with long-term memory and all four regions of interest included in the same model; the difference in anterior coherence remained significantly negatively correlated with long-term memory capacity and with a higher explanatory power compared to the other brain regions. Columns 3–12 show the “horse race” regression with the four regions of interest and different working memory test.
