Since the discovery of cognitive maps in rodent hippocampus (HC), the cognitive map has evolved from originally referring to spatial representations encoding locations and objects in Euclidean spaces to a general low-dimensional organization of information along selected feature dimensions. A cognitive map includes hypothetical constructs that bridge between environmental stimuli and the final overt behavior. To neuroeconomists, utility and utility functions are such constructs with neurobiological basis that drive choice behavior. Emergence of distinct functional neuron groups in the primate orbitofrontal cortex (OFC) during simple economic choice indicates the formation of an abstract cognitive map for organizing information of goods for value computation. Experimental evidence suggests that organization of neuronal activity in such cognitive map reflects the abstraction of core task features. Thus, such map can be adapted to accommodate economic choices under various task contexts.
自啮齿动物海马体（HC）中发现认知地图以来，认知地图已经从最初指的是在欧几里得空间中编码位置和物体的空间表示发展为沿着选定特征维度的信息的一般低维组织。认知地图包括假设的结构，这些结构在环境刺激和最终的明显行为之间架起了桥梁。对于神经经济学家来说，效用和效用函数是具有神经生物学基础的此类结构，它们驱动选择行为。在简单的经济选择中，灵长类动物眶额皮层（OFC）中出现了不同的功能神经元群，这表明为了进行价值计算而对商品信息进行组织的抽象认知地图的形成。实验证据表明，这种认知地图中神经元活动的组织反映了核心任务特征的抽象化。因此，这种地图可以适应各种任务环境下的经济选择。
