Abstract

Background Previous evidence has shown that genetic variations in the serotonergic system contribute to individual differences in personality traits germane to impulse control. The monoamine oxidase-A (MAO-A) gene, coding for an enzyme primarily involved in serotonin and noradrenaline catabolism, presents a well-characterized functional polymorphism consisting of a variable number of tandem repeats in the promoter region, with high-activity and low-activity variants. High-activity allele carriers have higher enzyme expression, lower amine concentration, and present higher scores on behavioral measures of impulsivity than low-activity allele carriers.Methods We studied the relationship of this polymorphism to brain activity elicited by a response inhibition task (Go/NoGo task), using blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging in 24 healthy men.Results Direct comparison between groups revealed a greater BOLD response in the right ventrolateral prefrontal cortex (Brodmann's area [BA] 45/47) in high-activity allele carriers, whereas a greater response in the right superior parietal cortex (BA 7) and bilateral extrastriate cortex (BA 18) was found in low-activity allele carriers.Conclusions These data suggest that a specific genetic variation involving serotonergic catabolism can modulate BOLD response associated with human impulsivity.

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?

  • Polymorphisms of the MAO-A gene that increase MAO-A activity are associated with increased activity in the right IFG and ACC and decreased activity in the superior parietal cortex during action restraint.

    “Polymorphisms of the MAO-A gene, which increase MAO-A activity, were associated with increased activity in the right IFG and ACC and decreased activity in the superior parietal cortex during action restraint (Passamonti et al., 2006).”

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.
