Impaired emotional processing in a patient with a left posterior insula-SII lesion
Abstract
The present case-report investigated the influence of a lesion in the left posterior insula-SII cortices on the processing of emotions. MB and 16 normal controls explicitly rated the valence and the intensity of both facial expressions and emotional words. In addition, they had to perform a number comparison task and a lexical decision task without focusing their attention on emotional components of stimuli. MB identified the valence of emotional words as well as the control group. Nevertheless, she provided higher intensity scores for disgusted words and her responses in the lexical decision task were significantly delayed for these stimuli. In addition, MB's response times were not differently influenced by the presence of irrelevant emotional faces. However, she explicitly identified fewer facial expressions of disgust and she assessed them as significantly less intense. This pattern of results contributes to highlight the psychological and behavioral disorders observed after a left posterior insular stroke.

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.
