神经科学研究强调，眶额皮质（OFC）的关键功能是编码价值。联想学习研究表明，刺激线索的OFC表征反映了预期结果的预测价值。神经经济学研究表明，OFC从离散的商品中提炼出抽象的价值表示，以优化选择。虽然基于价值的模型为许多不同的发现提供了很好的解释力，但这些模型通常与产生这些价值表征的刺激和商品脱节。无论是在理论上还是在经验上，对于对象同一性的必要合作作用都没有作出什么规定，没有这种作用，价值就会从其根源上成为孤儿。作为修复身份价值的一步，本综述提供了OFC研究的重点嗅觉调查，包括我们实验室的新工作，以突出该区域在刺激特异性预测编码中知觉结果和期望值的基本参与。
Neuroscientific research has emphatically promoted the idea that the key function of the orbitofrontal cortex (OFC) is to encode value. Associative learning studies indicate that OFC representations of stimulus cues reflect the predictive value of expected outcomes. Neuroeconomic studies suggest that the OFC distills abstract representations of value from discrete commodities to optimize choice. Although value-based models provide good explanatory power for many different findings, these models are typically disconnected from the very stimuli and commodities giving rise to those value representations. Little provision is made, either theoretically or empirically, for the necessary cooperative role of object identity, without which value becomes orphaned from its source. As a step toward remediating the value of identity, this review provides a focused olfactory survey of OFC research, including new work from our lab, to highlight the elemental involvement of this region in stimulus-specific predictive coding of both perceptual outcomes and expected values.
