Coherence spectra for the period T1. Superimposed frequency-coherence plots for each subject in the beta- and gamma-range for the three conditions W1 (dotted line), W2 (thin line) and W3 (thick line) during the transitory period T1. The confidence level at 95% is marked with a horizontal thin line.
