Table 4 Frequency of activations in AR and eAR – dependency on selected threshold for statistical inferences and applied smoothing filter-kernel. Frequency of activation in AR around 65–82% were reached with p < 0.001 for studies without anesthesia and p < 0.01 for those with anesthesia (bold, S = [20 mm]3). Gray background indicates which values have been compared with respect to significance of difference (explicitly assigned by superscripts)
