Ongoing oscillations have been shown to be modulated in different frequency bands following phasic, tonic as well as periodic thermonociceptive stimulation. Yet, it remains unclear whether these modulations are related to pain perception, saliency (i.e., the ability of a stimulus to stand out from its environment) or solely the intensity of these stimuli. Thirty-five participants were recruited Tto investigate the relationship between pain perception and ongoing oscillations as well as the factors likely to modulate them, we combininged a sustained periodic thermonociceptive stimulation paradigm including periodic oddball events with a frequencytagging analysis approach. Oddballs were delivered either at a higher or lower intensity (“high oddball” vs “low oddball” condition) than baseline stimuli. Continuous ratings of pain perception were collected during the stimulation to track participants’ perception.
