Figure 2

Partial regression plots displaying the association between Flanker interference effect on reaction time (RT) and (a) gamma current density in left dlPFC, after controlling for model covariates (site and gamma activity in the right dlPFC, BA 24'/32' (dACC) and BA 24/32 (rACC), (b) alpha2 current density in the right dlPFC, controlling for site and alpha2 activity in the left dlPFC, dACC, and rACC, (c) theta current density in dACC, controlling for theta activity in rACC, and left and right dlPFC, and (d) alpha2 current density in dACC, controlling for alpha2 activity in rACC, and left and right dlPFC. The theta dACC effect is reduced to a trend level (β=−0.29, p=0.060) in the model after removing the residual value at the bottom right corner of panel c. It should be noted that the zero-order correlation (ie, excluding model covariates) between theta dACC and interference effect on RT is significant (r=−0.25; p=0.026).
