Value signals in the brain are important for learning, decision-making, and orienting behavior toward relevant goals. Although they can play different roles in behavior and cognition, value representations are often considered to be uniform and static signals. Nonetheless, contextual and mixed representations of value have been widely reported. Here, we review the evidence for heterogeneity in value coding and dynamics in the orbitofrontal cortex. We argue that this diversity plays a key role in the representation of value itself and allows neurons to integrate value with other behaviorally relevant information. We also discuss modeling approaches that can dissociate potential functions of heterogeneous value codes and provide further insight into its importance in behavior and cognition.

眶额群体中的异质值编码。


大脑中的价值信号对于学习、决策以及将行为导向相关目标非常重要。尽管它们在行为和认知中可以发挥不同的作用，但价值表示通常被认为是统一的静态信号。尽管如此，价值的上下文和混合表征已被广泛报道。在这里，我们回顾了眶额皮层价值编码和动力学异质性的证据。我们认为，这种多样性在价值本身的表征中发挥着关键作用，并允许神经元将价值与其他行为相关信息整合起来。我们还讨论了可以分离异质价值代码的潜在功能的建模方法，并进一步深入了解其在行为和认知中的重要性。 （PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
