Figure 3c,d topographic analyses with bootstrap-based one-way RM-ANOVAs at each channel after training. The article states "the majority of channels displayed a main effect attributable to Time" and interprets this as "significant reconfiguration in neural processing after the training intervention."

"The topographic map showed an expansion o fn e g a t i v ea r e a si nt h ef rontal-central lobe with an increase in amplitude and a narrowing of positive areas in t he parieto-occipital lobe with an increase in amplitude"
