Figure 5.

Lateral top view of the left and right IPS activation for the comparison event-absent ARpar > IRpar, thresholded at p < 0.001 uncorrected, revealed by EEG-informed fMRI analysis including SSSEPs as parametric modulator. The bar graphs on the left and right display normalized contrast estimates for the parametric modulation in left and right IPS. Error bars indicate the SEM. The figure shows that activity in the IPS scaled with the amplitude of the steady-state responses; i.e., the higher the steady-state amplitude, the higher the IPS BOLD activity. Note that we have to be cautious with the reference value because we did not assess a reliable baseline activity.
