Neural correlates of word processing influenced by painful primes.
PLOS ONE. DOI 10.1371/journal.pone.0295148
Abstract: The administration of painful primes has been shown to influence the perception of
successively presented semantic stimuli. Painful primes lead to more negative valence
ratings of pain-related, negative, and positive words than no prime. This effect was
greater for pain-related than negative words. The identities of this effect’s neural
correlates remain unknown. In this EEG experiment, 48 healthy subjects received
noxious electrical stimuli of moderate intensity. During this priming, they were
presented with adjectives of variable valence (pain-related, negative, positive, an neutral).
The triggered event-related potentials were analyzed during N1 (120–180 ms), P2 (170–260 ms),
P3 (300–350 ms), N400 (370–550 ms), and two late positive complex components (LPC1 [650–750 ms]
and LPC2 [750–1000 ms]). Larger eventrelated potentials were found for negative and pain-related words compared to positive words in later components (N400, LPC1, and LPC2), mainly in the frontal regions.
Early components (N1, P2, and P3) were less affected by the word category but were
by the prime condition (painful vs. no stimulation). Later components (LPC1, LPC2)
were not affected by the prime condition. An interaction effect involving prime and word
category was found on the behavioral level but not the electrophysiological level.
This finding indicates that the interaction effect does not directly translate from the
behavioral to the electrophysiological level. Possible reasons for this discrepancy are discussed.
The data repository contains raw EEG data and EEG log files as well as trigger information for
Brain Vision Analyzer (compatible with EEGLAB), and
subjective parameters about pain and control conditions for 48 individuals.
Meta information about data structure are included.
Detailed information about methods and data analysis are presented in the above-mentioned paper.
