20.500.12556/DKUM-97474 Neurophysiological potentials mediating the influence of social support on pain The supportive presence of a significant other can act as an efficient analgesic. However, neurophysiological mechanisms of this effect have not been adequately explored. The current EEG study, using electrical pain stimulation, explored neurophysiological mechanisms mediating the influence of romantic partner’s presence on acute pain perceptions. Female participants (N = 41, mean age = 27.44, SD = 7.93) were exposed to painful stimuli in two alternating conditions: a) while receiving support from a male romantic partner via a live camera interaction and b) in the absence of partner support. It was hypothesised that social support would influence subjective reports and pain-related potentials, and that early and late pain-related ERPs would mediate the effect of social support on pain perception. Multilevel mediation analysis showed that partner support predicted lower pain unpleasantness and pain intensity. Additionally, the relationship between social support and both outcomes (unpleasantness and intensity) was mediated by neurophysiological components, the N130 potential at the C4 electrode, and the P300 potential at the central-parietal and parietal clusters. Exploratory whole-brain mediation confirmed and extended the relevance of the P300 component at central and parietal locations as an important brain mediator of social support and pain. The current study identified early and late pain-related potentials as mediators between social support and pain, highlighting potential clinical use of this social non-pharmacological pain analgesic and providing an important foundation for further explorations of social pain regulation. Perspective: This investigation uncovered early and late pain-related potentials as neurophysiological mediators between social support and pain intensity as well as pain unpleasantness. The findings could potentially help with the development or introduction of non-pharmacological methods to (additionally) reduce pain during painful procedures. social regulation pain regulation EEG mediators pain related potentials whole-brain mediation socialna regilacija uravnavanje bolečine EEG mediatorji z bolečino povezani potenciali vsemožganska mediacija true false true Angleški jezik Slovenski jezik Znanstveno delo 2026-03-12 03:07:46 2026-03-31 12:45:18 2026-08-20 10:20:51 0000-00-00 00:00:00 2026 0 0 str. 1-9 št. članka 106247 Letn. 42 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2026-02-22 2026-02-27 159.96 271067139 10.1016/j.jpain.2026.106247 1526-5900 RAZ_Horvat_Marina_2026.pdf RAZ_Horvat_Marina_2026.pdf 1 AA62C76B8AECAA9744482B470F22BCB6 4c4b52dfcc4c7c155c38bf302843ec9600da6103d03bb0614a5a7ed12dc9cb52 ab8685b1-2cee-11f1-b3ef-00155d0001a1 https://dk.um.si/Dokument.php?lang=slv&id=204927 https://www.sciencedirect.com/science/article/pii/S1526590026000659?via%3Dihub 1 44129a15-1db8-11f1-b92a-00155d580e1a https://dk.um.si/Dokument.php?lang=slv&id=204440 Filozofska fakulteta 0 0 0
