Source dipole moments (mean ± SD, nAm) in select time epochs in high and low pain catastrophisers during viewing pain or non-pain pictures. F values (with degrees of freedom), P values and effect sizes (η2 p) for ANOVA comparisons are also shown. C = main effect of catastrophising, P = main effect of picture type, C*I = interaction effect. Source 1 = rostral anterior cingulate cortex 280–336 ms; Source 2 = left paraphippocampal gyrus 596–828 ms; Source 3 = right parahippocampal gyrus 580–664 ms; Source 4a-4b = posterior cingulate cortex 384–452 ms and 756–1144 ms respectively.
