Emotional states provide an ever-present source of contextual information that should inform behavioral goals. Despite the ubiquity of emotional signals in our environment, the neural mechanisms underlying their influence on goal-directed action remains unclear. Prior work suggests that the lateral frontal pole (FPl) is uniquely positioned to integrate affective information into cognitive control representations. We used pattern similarity analysis to examine the content of representations in FPl and interconnected mid-lateral prefrontal and amygdala circuitry. Healthy participants ( = 37; = 21 females) were scanned while undergoing an event-related Affective Go/No-Go task, which requires goal-oriented action selection during emotional processing. We found that FPl contained conjunctive emotion-action goal representations that were related to successful cognitive control during emotional processing. These representations differed from conjunctive emotion-action goal representations found in the basolateral amygdala. While robust action goal representations were present in mid-lateral prefrontal cortex, they were not modulated by emotional valence. Finally, converging results from functional connectivity and multivoxel pattern analyses indicated that FPl emotional valence signals likely originated from interconnected subgenual anterior cingulate cortex (ACC) (BA25), which was in turn functionally coupled with the amygdala. Thus, our results identify a key pathway by which internal emotional states influence goal-directed behavior. Optimal functioning in everyday life requires behavioral regulation that flexibly adapts to dynamically changing emotional states. However, precisely how emotional states influence goal-directed action remains unclear. Unveiling the neural architecture that supports emotion-goal integration is critical for our understanding of disorders such as psychopathy, which is characterized by deficits in incorporating emotional cues into goals, as well as mood and anxiety disorders, which are characterized by impaired goal-based emotion regulation. Our study identifies a key circuit through which emotional states influence goal-directed behavior. This circuitry comprised the lateral frontal pole (FPl), which represented integrated emotion-goal information, as well as interconnected amygdala and subgenual ACC, which conveyed emotional signals to FPl.
情绪状态提供了一种不断变化的情境信息来源,这些信息应该能够为行为目标提供信息。尽管情绪信号在我们的环境中无处不在,但它们对目标导向行为的影响的神经机制尚不清楚。先前的研究表明,外侧额极(FPl)是将情感信息整合到认知控制表示中的独特位置。我们使用模式相似性分析来检查 FPl 及其相互连接的中侧前额叶和杏仁核电路中的表示内容。健康参与者(= 37;= 21 名女性)在进行与情绪相关的“情感 Go/No-Go”任务时接受了扫描,该任务需要在情绪处理过程中进行有目标的行动选择。我们发现 FPl 包含与情绪处理过程中成功认知控制相关的联合情绪-动作目标表示。这些表示与基底外侧杏仁核中的联合情绪-动作目标表示不同。虽然在中侧前额叶皮层中存在强大的动作目标表示,但它们不受情绪效价的调节。最后,来自功能连接和多体素模式分析的收敛结果表明,FPl 情绪效价信号可能源自相互连接的扣带回下侧前扣带皮层(BA25),扣带回下侧前扣带皮层又与杏仁核功能耦合。因此,我们的研究结果确定了内部情绪状态影响目标导向行为的关键途径。日常生活中最佳的功能需要灵活适应动态变化的情绪状态的行为调节。然而,情绪状态如何影响目标导向行为仍然不清楚。揭示支持情绪-目标整合的神经结构对于我们理解诸如精神变态等障碍至关重要,精神变态的特征是将情绪线索纳入目标的能力不足,以及情绪和焦虑障碍,其特征是基于目标的情绪调节受损。我们的研究确定了一个关键的电路,通过这个电路情绪状态影响目标导向行为。该电路包括外侧额极(FPl),它代表了整合的情绪-目标信息,以及相互连接的杏仁核和扣带回下侧,它们将情绪信号传递给 FPl。
