Association and dissociation between laser-evoked potentials and pain perception
Abstract
We investigated the relation between the subjective sensation of pain and two different components of the laser evoked potential, namely the vertex response (N220-P350) and an earlier lateralized response (middle-latency NP160). Brain responses to laser stimuli were obtained in 15 subjects under attentive and distractive conditions. Although stimulus intensity was kept constant, it was perceived as significantly higher when subjects attended the stimulation. There was a positive correlation between subjective intensity perception and the amplitude of the vertex potential, but no correlation existed with the middle-latency component. While laser vertex potentials may reflect attentional/perceptual mechanisms that determine subjective experience, the NP160 behaves as a pre-perceptual sensory response that should be advantageous in the assessment of early cortical pain processing.

In the citing paper
“The early N1 component, reflecting the activity of cortical generators in the contralateral operculoinsular and primary somatosensory cortices 30, 63, is largely driven by the magnitude of the ascending nociceptive input, representing an early stage of sensory processing before the perceptual outcome of the nociceptive input is determined 48, 64, 65.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
