Abstract

Interaction between Pavlovian and instrumental control systems is key for adaptive motivated behavior, but also plays an important role in various neuropsychiatric disorders, including depression, addiction, and anxiety. Here, we employed the flouorodopa positron emission tomography ([¹⁸F]-DOPA PET) in healthy participants (N = 100) to assess whether dopamine synthesis capacity (Ki), specifically in the ventral striatum, accounts for individual variation in Pavlovian-to-instrumental transfer (PIT). Surprisingly, this was not the case. Rather, the relationship of ventral striatal Ki with PIT depended on working memory (WM) capacity. Ventral striatal dopamine boosted the effects of Pavlovian cues on instrumental responding to a greater degree in participants with higher WM capacity. Caution is warranted to interpret this post hoc four-way interaction given the modest sample size. Nonetheless, these results chime with prior findings demonstrating that dopaminergic drugs boost Pavlovian biases to a greater degree in participants with greater WM capacity and highlight the importance of interactions between striatal dopamine and WM capacity.

纹状体多巴胺对巴甫洛夫偏向的影响。一项大型[¹⁸F]-多巴PET研究。
巴甫洛夫控制系统和工具控制系统之间的相互作用是适应性动机行为的关键,但在各种神经精神疾病中也起着重要作用,包括抑郁、成瘾和焦虑。在本研究中,我们使用了健康参与者(N = 100)的氟多巴正电子发射断层扫描([¹⁸F]-DOPA PET)来评估多巴胺合成能力(Ki),特别是腹侧纹状体,是否解释了巴甫洛夫-工具转移(PIT)的个体差异。令人惊讶的是,事实并非如此。相反,腹侧纹状体Ki与PIT的关系取决于工作记忆(WM)容量。腹侧纹状体多巴胺在更高WM能力的参与者中更大程度地增强了巴甫洛夫线索对工具性反应的影响。考虑到适度的样本量,解释这种事后的四向相互作用是有必要的。尽管如此,这些结果与先前的研究结果一致,表明多巴胺能药物在更大程度上促进了脑记忆能力更强的参与者的巴甫洛夫偏见,并强调了纹状体多巴胺和脑记忆能力之间相互作用的重要性。(PsycInfo数据库记录(c) 2023 APA,版权所有)。
