EEG-power in EX1 and EX2. Error bars represent the standard error of the mean. Significance level: 0.01 < ; 0.001 < ; ; trend: () 0.05 < . (a) EX1 EEG power amplitude values alpha: baseline-stereo , baseline-pyramide , baseline-sphere ; beta2: baseline-stereo , baseline-pyramide , baseline-sphere . (b) EX2 EEG power amplitude values. Delta: baseline-stereo ; alpha: baseline-pyramid , baseline-sphere , baseline-cube , baseline-stereo ; beta1: baseline-pyramid ; beta2: baseline-pyramid , baseline-sphere , baseline-cube ; gamma: baseline-pyramid .
