The monetary incentive delay task breaks down reward processing into discrete stages for fMRI analysis. Here we look at anticipation of monetary gain and loss contrasted with neutral anticipation. We meta-analysed data from 15 original whole-brain group maps (n = 346) and report extensive areas of relative activation and deactivation throughout the whole brain. For both anticipation of gain and loss we report robust activation of the striatum, activation of key nodes of the putative salience network, including anterior cingulate and anterior insula, and more complex patterns of activation and deactivation in the central executive and default networks. On between-group comparison, we found significantly greater relative deactivation in the left inferior frontal gyrus associated with incentive valence. This meta-analysis provides a robust whole-brain map of a reward anticipation network in the healthy human brain.

健康奖励预期的神经基质：货币激励延迟任务中功能磁共振成像结果的元分析

货币激励延迟任务将奖励处理分解为用于 fMRI 分析的离散阶段。在这里，我们看一下货币收益和损失的预期与中性预期的对比。我们对来自 15 个原始全脑组图（n = 346) 并报告整个大脑中广泛的相对激活和失活区域。对于收益和损失的预期，我们报告了纹状体的强大激活，假定的显着网络的关键节点的激活，包括前扣带回和前岛叶，以及中央执行网络和默认网络中更复杂的激活和失活模式。在组间比较中，我们发现与激励效价相关的左侧额下回的相对失活明显更大。该荟萃分析提供了健康人脑中奖励预期网络的强大全脑图。
