Abstract

Background Functional neuroimaging experiments in healthy control subjects have shown that choosing between small and immediate rewards versus larger but deferred rewards in delay discounting (DD) tasks recruits mesofrontal and lateral frontal cortex. Might individual differences in frontocortical gray matter morphology be related to preference for immediate reward?Methods We related DD in a laboratory decision-making task to proportional frontocortical gray matter (GM) volumes calculated from segmented magnetic resonance images in 29 healthy adults.Results Dorsolateral and inferolateral frontal cortex GM volumes (corrected as a proportion of whole cerebral brain volume) each correlated inversely with preference for immediate gratification during decision making, as indexed by DD constant k. Conversely, neither proportional orbitofrontal or mesofrontal cortex GM volume nor cerebral brain volume (CBV) or total intracranial volume (ICV; a measure of maximal brain growth) significantly correlated with severity of DD.Conclusions Severity of discounting of delayed rewards correlates with proportional lateral frontocortical GM morphology but not with whole brain measures. In light of evidence of frontocortical abnormalities in substance dependence and sociopathy, future studies can assess whether reduced frontocortical volume itself is a morphological marker or risk factor for inability to delay gratification in psychiatric disorders.

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?

  • Delay discounting depends on prefrontal cortex including orbitofrontal cortex.

    “Interestingly, delay discounting seems to depend on the function of the ventral striatum (104) and of the PFC, including OFC (105) and its connections to the NAc (106), and is sensitive to DA manipulations (107).”

  • Delay discounting seems to depend on the function of ventral striatum and of the PFC, including OFC, and is sensitive to DA manipulations.

    “Delay discounting seems to depend on the function of ventral striatum (Gregorios-Pippas et al 2009) and of the PFC, including OFC (Bjork et al 2009), and is sensitive to DA manipulations (Pine et al 2010).”

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.
