Body mass predicts orbitofrontal activity during visual presentations of high-calorie foods

Killgore, William D. S., Yurgelun-Todd, Deborah A.·2005·NeuroReport

Abstract

Little is known about the relationship between weight status and reward-related brain activity in normal weight humans. We correlated orbitofrontal and anterior cingulate cortex activity as measured by functional magnetic resonance imaging with body mass index in 13 healthy, normal-weight adult women as they viewed images of high-calorie and low-calorie foods, and dining-related utensils. Body mass index correlated negatively with both cingulate and orbitofrontal activity during high-calorie viewing, negatively with orbitofrontal activity during low-calorie viewing, and positively with orbitofrontal activity during presentations of nonedible utensils. With greater body mass, activity was reduced in brain regions important for evaluating and modifying learned stimulus-reward associations, suggesting a relationship between weight status and responsiveness of the orbitofrontal cortex to rewarding food images.

  • Compared with normal-weight individuals, obese individuals presented with pictures of high-calorie food show increased neural activation in reward and motivation circuits including NAc, dorsal striatum, OFC, ACC, amygdala, hippocampus, and insula.

    “compared with normal-weight individuals, obese individuals who were presented with pictures of high-calorie food (stimuli to which they are conditioned) showed increased neural activation in regions that are part of reward and motivation circuits (NAc, dorsal striatum, OFC, ACC, amygdala, hippocampus and insula) (90).”

  • Compared with normal-weight individuals, obese individuals viewing high-calorie food pictures show increased activation in reward and motivation circuits (NAc, dorsal striatum, OFC, ACC, amygdala, hippocampus, insula).

    “Compared with normal-weight individuals, obese individuals observing pictures of high-calorie food (stimuli to which they are conditioned) showed increased activation in regions of the reward and motivation circuits (NAc, dorsal striatum, orbitofrontal cortex [OFC], anterior cingulate cortex [ACC], amygdala, hippocampus, and insula) (50).”

  • Compared with normal-weight individuals, obese individuals presented with pictures of high-calorie food showed increased neural activation in regions that are part of reward and motivation circuits, including NAc, dorsal striatum, OFC, ACC, amygdala, hippocampus and insula.

    “Similarly, compared with normal-weight individuals, obese individuals who were presented with pictures of high-calorie food (stimuli to which they are conditioned) showed increased neural activation in regions that are part of reward and motivation circuits (NAc, dorsal striatum, OFC, ACC, amygdala, hippocampus and insula) (Killgore and Yurgelun-Todd 2005).”

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.
