Key result
Heat-induced pain correlates with higher EEG alpha-bandpower than cold stimulation in healthy subjects.
Why the study?
This research explores gender differences in pain perception by analyzing electroencephalographic signals during thermal sensations.
How do EEG signals change in healthy subjects when stimulated by heat versus cold?
Cross-Sectional (n=10)
How do EEG signals change in healthy subjects when stimulated by heat versus cold?
Alpha-bandpower on EEG is higher during heat-induced pain compared to cold-induced pain, which may help in identifying pain thresholds.
This research explores gender differences in pain perception by analyzing Electroencephalographic (EEG) signals. The study involves 10 healthy subjects and includes induction of thermal sensations, and analysis of bandpower changes before and after stimuli. According to the results, alpha-bandpower is higher when the subjects feel pain with heat than with cold. Clinical Relevance– This work might be considered as an approach to find a pain threshold in men and women.

Sánchez-Vázquez et al. (2023) conducted a cross-sectional in Healthy (n=10). Heat stimulation vs. Cold stimulation was evaluated on Alpha-bandpower changes. Alpha-bandpower in EEG signals is higher when healthy subjects feel pain induced by heat compared to cold stimulation.
