How expectations shape pain

Atlas, Lauren Y., Wager, Tor D.·2012·Neuroscience Letters

Abstract

Pain is highly modifiable by psychological factors, including expectations. However, pain is a complex phenomenon, and expectations may work by influencing any number of processes that underlie the construction of pain. Neuroimaging has begun to provide a window into these brain processes, and how expectations influence them. In this article, we review findings regarding expectancy effects on brain markers of nociception and how expectations lead to changes in subjective pain. We address both expectations about treatments (placebo analgesia and nocebo effects) and expectations about the environment (e.g. expectations about pain itself). The body of work reviewed indicates that expectancies shape pain-intensity processing in the central nervous system, with strong effects on nociceptive portions of insula, cingulate and thalamus. Expectancy effects on subjective experience are driven by responses in these regions as well as regions less reliably activated by changes in noxious input, including the dorsolateral prefrontal cortex and the orbitofrontal cortex. Thus, multiple systems are likely to interact and mediate the pain-modulatory effects of expectancies. Finally, we address open questions regarding the psychological processes likely to play an intervening role in expectancy effects on pain.

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.
