TANOVA, average topographies, t-maps and microstate analyses of the Go condition in the sport-specific Go/NoGo task. (A) The curve represents the p-values from the TANOVA plotted for each time point from 0 to 800 ms after stimulus onset. The period of significant topographic differences (p < .05) is highlighted in pink. (B) Mean ERP topographies were computed for each group separately over 100 ms time intervals. The topographies were normalized (GFP = 1). Red and blue indicate positive and negative potential values, respectively. The t-map contrasting each group with the other groups is shown for the POI divided into two time periods, namely, from 206 to 300 ms and from 300 to 466 ms. Positive (in red) and negative (in blue) t-values indicate more positive and more negative potentials regarding the order of the group contrast (T-E indicates the data from the table tennis group were compared to the data from the endurance group). The p-values from the TANOVA of the t-maps are displayed. (C) The topographies of the three microstate maps obtained from the cross-validation procedure and their duration are displayed for the three groups. Red and blue indicate positive and negative potential values, respectively. The topographies were normalized (GFP = 1). The colored frame surrounding each map corresponds to their occurrence in the graph below. (D) The GFP of the microstate maps is displayed as a function of time for each group. B = basketball; T = Table tennis; E = endurance. The topographies displayed in (A), (B) and (C) have been generated via MATLAB (http://www.mathworks.com/).
