Urge to scratch represented in the human cerebral cortex during itch

Abstract

1. We used functional positron emission tomography (PET), measuring regional cerebral blood flow (rCBF) as an index of neuronal activity, to investigate the central processing of itch in 10 healthy volunteers subjected to intracutaneous injections of histamine. 2. The study has unraveled a central representation that depicts a motor intention of the urge to scratch contingent on the perception of unpleasant itch. The coactivation of the anterior cingulate cortex (ACC), supplementary motor area (SMA), premotor area (PM), and inferior parietal lobule (IPL) substantiates that the posterior sector of the ACC (Brodmann 24) is related to the sensorial/affectional aspect of the event. The premotor cortical areas (SMA, PM) and the IPL may participate in the preparation of an intended action.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The activity in SMA and pre-SMA during threat to the owned rubber hand reflects an urge to withdraw the hand rather than anxiety.

    “Thus, we suggest that the activity in SMA and pre-SMA in the present study reflects an urge to withdraw the hand, rather than anxiety, because this activity was not correlated with the anxiety ratings.”

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.
