Spatial Cognition: Grid Cells Support Imagined Navigation
Grid cells in the entorhinal cortex represent an animal's current location during navigation. A new study indicates that grid cells in humans also represent information about imagined movement and spatial orienting, suggesting that the entorhinal network has a flexible role in spatial representation.
متن کاملGrid-like Processing of Imagined Navigation
Grid cells in the entorhinal cortex (EC) of rodents [1] and humans [2] fire in a hexagonally distributed spatially periodic manner. In concert with other spatial cells in the medial temporal lobe (MTL) [3-6], they provide a representation of our location within an environment [7, 8] and are specifically thought to allow the represented location to be updated by self-motion [9]. Grid-like signal...
متن کاملEgocentric organization of spatial activities in imagined navigation.
Studies on spatial frameworks suggest that the way we locate objects in imagined environments is influenced by the physical and functional properties of the world and our body. The present study provides evidence that such an influence also characterizes imagined navigation. In Experiment 1, participants followed spatial directions to construct an imagined path, while either keeping constant or...
متن کاملSailAway: Spatial Cognition in Sea Navigation
Pedestrians, bicyclists, car drivers, boat and airplane pilots, as well as other cognitive agents participating in public traffic must respect rules in order to avoid dangerous situations and to ensure a smooth flow of traffic. The SailAway project [1] investigates traffic and related navigational rules from a formal and computational point of view. The aim is to enable artificial cognitive age...
متن کاملUsing Grid Cells for Navigation
Mammals are able to navigate to hidden goal locations by direct routes that may traverse previously unvisited terrain. Empirical evidence suggests that this "vector navigation" relies on an internal representation of space provided by the hippocampal formation. The periodic spatial firing patterns of grid cells in the hippocampal formation offer a compact combinatorial code for location within ...
