Profiles showing the degrees of relative interdependencies (in units of ς) in the γ band for musicians relative to non-musicians at resting conditions: with eyes open (top) and eyes closed (bottom). Results were averaged over windows, subjects within each group, and for all possible electrode combinations for each electrode. For profile connected by an asterisk, significance level was computed while assessing the degree of influence of each electrode region on other electrode regions (“diverging node”). The other profile connected by an open circle exhibits the average property of each electrode considering it being influenced by others (“converging node”). The two horizontal lines (ς = ±2.33) represent the line of significance (p < 0.01) i.e., any entry above the higher line indicates that the degree of interdependency in musicians is significantly higher than non-musicians and any entry below the lower line indicates higher interdependency in non-musicians. No significant differences were found between the two groups at resting conditions.
