Abstract

Abstract A better understanding of the cortical processes underlying attentional modulation of visceral and somatic pain in health are essential for interpretation of future imaging studies of hypervigilance towards bodily sensations which is considered to be an aetiologically important factor in the heightened pain reported by patients with irritable bowel syndrome and fibromyalgia. Twelve healthy subjects were recruited for this study. Simultaneous trains of electrical pulses (delivered to either the rectum or lower abdomen) and auditory tones lasting 6 s were delivered to the subjects during a whole‐brain functional scan acquisition. Subjects were instructed to attend to the auditory tones (distracter task) or electrical pulses (pain task). Pain intensity ratings were significantly lower during the distraction task compared with the pain task (P < 0.01) in both sensory modalities. The left primary somatosensory cortex increased in activity with increasing pain report, during attention to visceral pain. Bilateral anterior insula (aIns) cortex activity increased with increasing somatic pain report independent of the direction of attention. Conversely, the primary and secondary auditory cortices significantly increased in activation with decreased pain report. These results suggest that pain intensity perception during attentional modulation is reflected in the primary somatosensory cortex (visceral pain) and aIns cortex activity (somatic pain).

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Physical and psychological stress, cognition, and early life experience can affect intestinal sensory perception.

    “For example, it has been shown that physical and psychological stress (112), cognition (e.g., attention vs. distraction to aversive stimulus) (55), and early life experience (e.g., sexual and physical abuse) (39, 149) can affect intestinal sensory perception.”

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.
