Localization and statistics of the peak voxels for the correlation analyses between differential SCRs in the FIR and neuronal activation in the contrast CS+ minus CS− in the extinction phase
| Group | Brain region | x | y | z | Tmax | Pcorr. | r |
|---|---|---|---|---|---|---|---|
| All participants | No significant correlation | ||||||
| Men | No significant correlation | ||||||
| LU women | No significant correlation | ||||||
| OC women | R ACC | 12 | 18 | 27 | 4.00 | 0.055 | 0.641 |
| R amygdala | 24 | 3 | −24 | 3.99 | 0.013 | 0.640 | |
| R thalamus | 15 | −18 | −3 | 3.75 | 0.044 | 0.616 | |

Results are listed for all participants as well as separately for men, LU and OC women within the respective ROI. In order to gain a quantitative measure for the magnitude of these correlations, we calculated the correlation coefficients r for the resulting brain structures using the t-values at the peak voxels of the respective analysis (cf. Rosenthal, 1994).
The significance threshold was Pcorr < 0.05 (FWE-corrected according to SPM8; small volume correction); trends up to Pcorr < 0.10 are shown. All coordinates (x, y, z) are given in MNI space. L = left and R = right.
