From: Cortical reorganization to improve dynamic balance control with error amplification feedback
The adjacent matrices of t values that contrast PLI values of all electrode pairs between the EA and RE conditions. A contrasting wiring diagram on the scalp shows the topological distributions of the supra-threshold connectivity tuned to error amplification (EA vs. RE)(|t |> 2.898, p < .005). It is worth noting that EA results in reductions of the prefrontal-parietal/occipital connectivity (alpha/beta bands) and right tempo-parietal connectivity (theta/alpha bands). Meanwhile, EA also enhances fronto-centro-parietal connectivity (theta/alpha bands) and right temporo-frontal/temporo-parietal connectivity (beta band). (Red line: EA supra-threshold connectivity > RE supra-threshold connectivity, p < .005; Blue line: RE supra-threshold connectivity > EA supra-threshold connectivity, p < .005).
