Flavor processing: more than the sum of its parts

Abstract

We used positron emission tomography to evaluate differential processing of olfactory, gustatory and combined olfactory and gustatory (flavor) stimuli as indicated by comparison of evoked cerebral blood flow (CBF) changes during these conditions. We found significant CBF decreases in primary gustatory and secondary gustatory and olfactory cortices during simultaneous presentation compared with independent presentations of identical stimuli, suggesting that flavor processing is not represented by a simple convergence of its component senses. Additionally, CBF increases in the amygdala and basal forebrain were observed in a mismatched flavor condition versus a matched flavor condition, suggesting a role for these structures in processing novel or unpleasant stimuli.

Statistics

Recomputing p-values needs the paper’s full text.

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?

  • Increased BOLD response is observed in the orbitofrontal cortex and amygdala when taste and odour stimuli are presented in combination compared to the summed activity of taste and smell when presented alone.

    “increased blood oxygen level dependent (BOLD) response was observed in the orbitofrontal cortex (OFC) and amygdala when taste and odour stimuli are presented in combination, compared to the summed activity of taste and smell when pretended alone [149].”

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.
