As people find their way through their environment, objects at navigationally relevant locations can serve as crucial landmarks. The parahippocampal gyrus has previously been shown to be involved in object and scene recognition. In the present study, we investigated the neural representation of navigationally relevant locations. Healthy human adults viewed a route through a virtual museum with objects placed at intersections (decision points) or at simple turns (non-decision points). Event-related functional magnetic resonance imaging (fMRI) data were acquired during subsequent recognition of the objects in isolation. Neural activity in the parahippocampal gyrus reflected the navigational relevance of an object's location in the museum. Parahippocampal responses were selectively increased for objects that occurred at decision points, independent of attentional demands. This increase occurred for forgotten as well as remembered objects, showing implicit retrieval of navigational information. The automatic storage of relevant object location in the parahippocampal gyrus provides a part of the neural mechanism underlying successful navigation.Studies on the neural basis of navigation have consistently shown the hippocampus to be crucially involved in the creation of an allocentric spatial representation of our environment 1-12 . The parahippocampal gyrus, a brain region highly interconnected with the hippocampus, has been implicated in the encoding of objects-in-place during navigation 5,6,13 , as well as in the processing of spatial visual scenes 14,15 . Successful navigation is facilitated by the presence of objects, or landmarks, at different locations along a route [16][17][18] . Not all objects along a route, however, are equally relevant for navigation. Whereas objects at intersections convey information about which of the possible paths is the correct one, objects placed at simple turns in the road are of much less significance. Behavioral studies have reported that objects placed at decision points (that is, intersections) are more likely to be remembered later than objects placed at non-decision points 17 . They are also regarded as more important when participants evaluate the quality of a route description 19 . How this distinction between navigationally relevant and irrelevant objects is stored and maintained in the brain is still unknown. To date, all studies have focused on the neural correlates of encoding spatial information during navigation. To find one's way back in a surrounding, however, the information about relevant locations needs to be available at a later moment in time. Therefore, it is likely that spatial information that is crucial for pathfinding is encoded and stored differently than information that is of less importance. Here we report event-related fMRI evidence for differential representation of objects in the parahippocampal gyrus as a function of their navigational relevance in a large-scale environment.In the study phase of the experiment, twenty healthy, right-handed human adu...
