Abbreviations: Fronto-central scalp (Fz, Fpz, Fp1, Fp2 electrodes of the 10–20 electrode system) estimating alpha generated in the anterior cingulate cortex; central scalp (C3, C3′, C4, C4′ of the 10–20 electrode system) estimating alpha generated in SI; temporal scalp (T7 and T8 of the 10–20 electrode system (Sharbrough et al. 1991)) estimating alpha generated in the parietal operculum/insula; CPT = cold pressor test (cold pain); im = intramuscular; sc = subcutaneous; ↑ pain > passive no task control; ↓ pain < passive no task control; n.c. pain = passive no task control.
