Figure 5.

Group average activation maps (13 subjects) and BOLD signal time courses within regions of interest in Experiment 1. The maps depict all brain regions showing positive or negative deflections of the BOLD signal in at least one of the three Δf_mod conditions compared to the baseline (t = 4.5, p < 0.002) for each of the two f_{mod A} (100, 300 Hz). Several regions that showed significant differences between conditions and f_{mod A} variants are labeled and the respective averaged BOLD signal time courses are assigned. Error bars represent SEM.
