Variation in the monoamine-oxidase-A (MAO-A) gene has been associated with volumetric changes in corticolimbic regions with differences in their response to relevant emotional tasks. Here we show no changes in baseline regional brain metabolism as a function of genotype indicating that, unchallenged, corticolimbic activity is not modulated by the MAO-A genotype.
单胺氧化酶A(MAO-A)基因的变异与皮质边缘区域的体积变化有关,这些区域对相关情感任务的反应存在差异。在这里,我们发现,作为基因型的一个函数,基线区域脑代谢没有变化,这表明在没有刺激的情况下,皮质边缘活动不受MAO-A基因型的调节。
