Experiential diversity promotes well-being in animal models. Here, using geolocation tracking, experience sampling and neuroimaging, we found that daily variability in physical location was associated with increased positive affect in humans. This effect was stronger for individuals who exhibited greater functional coupling of the hippocampus and striatum. These results link diversity in real-world daily experiences to fluctuations in positive affect and identify a hippocampal-striatal circuit associated with this bidirectional relationship.

现实世界的体验多样性和积极情感之间的关联与海马纹状体功能连接有关。

体验多样性促进动物模型的福祉。在这里，利用地理位置跟踪、经验采样和神经影像学，我们发现物理位置的日常变化与人类积极影响的增加有关。对于海马体和纹状体表现出更强的功能耦合的个体来说，这种效应更强。这些结果将现实世界日常体验的多样性与积极情绪的波动联系起来，并确定了与这种双向关系相关的海马-纹状体回路。
