..., the vestibular system provides input heading direction via its responses to rotations in the horizontal plane and is therefore essential for path integration ( Wiener et al., 1995 ). Vestibular afferents code best for frequencies <20 Hz ( Sadeghi et al., 2007 ), and we assume that smooth turning motions...

... the route, there is evidence that ants develop magnetically directed home and food vectors dependent upon path integration. A second experiment asked whether ants can use magnetic information contextually. In contrast to honeybees given a similar task, ants failed this test. Overall, we conclude...

... Euclidean cognitive maps, constructed on the basis of input from the path integration system. In this article, I review the rationale and behavioral evidence for this metric cognitive map hypothesis, and find it unpersuasive: in practice, there is little evidence for truly novel shortcuts in animals...

...Barbara Webb; Basil el Jundi; Almut Kelber; Barbara Webb ABSTRACT Insect navigation is strikingly geometric. Many species use path integration to maintain an accurate estimate of their distance and direction (a vector) to their nest and can store the vector information for multiple salient...

... generalization capabilities. This convergence of information may also explain the formation of grid cells in the medial EC if we suppose that: (1) path integration information is computed outside the EC, (2) this information is compressed at the level of the EC owing to projection (which follows a modulo...

When the ants were displaced locally to create a conflict between the home direction indicated by the path integrator and terrestrial landmarks, foragers oriented using landmark information exclusively...

Although natural landmarks are scarce and the ants mainly depend on path integration for returning to the starting point, they can also learn and use landmarks successfully...

This procedure prevented the distance and direction walked being affected by a home vector derived from path integration. Ants that were unfed walked...

...Ajay Narendra; Chloé A. Raderschall; Simon K. A. Robson SUMMARY The pressure of returning to and locating the nest after a successful foraging trip is immense in ants. To find their way back home, ants use a number of different strategies (e.g. path integration, trail following) and rely on a range...

... of either species on either continent: training and/or testing with and/or without artificial landmark arrays. We found that the open-terrain species C. fortis runs off its (path integration) home vector much more readily even in unfamiliar landmark settings than the cluttered-terrain species M. bagoti...

...Michael L. Walls; John E. Layne SUMMARY Foraging fiddler crabs ( Uca spp.) monitor the location of, and are able to return to, their burrows by employing path integration. This requires them to accurately measure both the directions and distances of their locomotory movements. Even though most...

...Kathrin Steck; Matthias Wittlinger; Harald Wolf SUMMARY Desert ants, Cataglyphis fortis, use a stride integrator as a distance gauge in their well-studied path integration system (while a skylight compass provides the direction gauge). To further scrutinize the mechanisms of the ant odometer, we...

...Doreen Heß; Julja Koch; Bernhard Ronacher SUMMARY On their foraging excursions, desert ants ( Cataglyphis fortis )navigate by means of path integration, exhibiting high precision even in undulating terrain. To avoid errors in their home vector the ants must measure the slopes of ascents...

We show in the first experiment...

...Patrick Bregy; Stefan Sommer; Rüdiger Wehner SUMMARY Foraging ants and bees use path-integration vectors and landmark cues for navigation. When in particular experimental paradigms the two types of information – vector-based and landmark-based information – are made to compete with each other...

...Tobias Merkle; Markus Knaden; Rüdiger Wehner SUMMARY Foraging desert ants return to their starting point, the nest, by means of path integration. If the path-integration vector has been run off but the nest has not yet been reached, the ants engage in systematic search behavior. This behavior...

...B. Ronacher; E. Westwig; R. Wehner SUMMARY When performing foraging trips desert ants of the genus Cataglyphis continuously process and update a `home vector' that enables them to return to their nest on the shortest route. This capacity of path integration requires two types of information: (i...
