Abstract To execute goal-directed behavior, retrieval of both context and object information is crucial. Despite the ubiquity of such contextual computations in daily navigation, the OPEN ACCESSneural mechanisms underlying this process in humans and its connection to behavCitation: Lv P, Chen D, Zhang C, Duan W, ior remain largely elusive.
