Brain responses during the anticipation period. (a) Activations for placebo > control were observed in the rACC and the ventral striatum. Parameter estimates are plotted for the rACC peak voxel. (b) The rACC showed enhanced placebo induced responses for the strong vs. weak placebo ((strong placebo > control) > (weak placebo > control)). Parameter estimates are plotted for the rACC peak voxel. Error bars indicate 90% confidence interval. Statistical t-maps are overlaid on an average structural image and the significance threshold is set to p < 0.005 (uncorrected) for visualization purposes only.
