We studied path integration in dogs, Canis familiaris, required to return to the starting point of L-shaped outward paths in the absence of landmark information. The analysis of the distributions of errors in the return direction and distance showed that the dogs made both systematic and random errors. They tended to overestimate by about 6 degrees the amount of turning required at the end of the outward path to take the correct return direction. Random angular errors were characterized by a… Expand

Egocentric path integration models and their application to desert arthropods.

- Journal of theoretical biology
- 2006

This work systematically review the four possible model descriptions of mathematically precise path integration, whereby it favour and elaborate the hitherto not used variant of egocentric cartesian coordinates, and proposes simple error indices depending on path geometry that will allow future experiments to rule out or corroborate certain error types.

Animal path integration: a model of positional uncertainty along tortuous paths.

- Mathematics, Medicine
- Journal of theoretical biology
- 2014

It is shown that increasing path tortuosity decreases positional uncertainty, true for long and short journeys, irrespective of whether a compass is used, or the level of noise, and that polar PI using a compass accumulates uncertainty in a manner similar to Cartesian PI without a compass. Expand

Homing by Path Integration When a Locomotion Trajectory Crosses itself

Results showed that path crossover does not always cause significant disruption in path integration processes, and the errors yielded from the path containing the crossover were not always larger than those observed in other paths. Expand

A Dynamic Bayesian Observer Model Reveals Origins of Bias in Visual Path Integration

- Computer Science, Biology
- 2017

The results suggest that visual path integration performance is limited largely by biases in processing optic flow rather than by suboptimal signal integration, which is better explained by a slow-speed prior than imperfect integration. Expand

A connectionist model of path integration with and without a representation of distance to the starting point

- Psychology

Path integration (dead reckoning) is the process by which animals use self-generated movement information to continuously update a representation of their position relative to some starting point.… Expand

Possible uses of path integration in animal navigation

- Psychology
- 2000

Path integration, in its simplest form, keeps track of movement from a starting point and so makes it possible to return to this point. Path integration can also be used to build a metric spatial… Expand

A Dynamic Bayesian Observer Model Reveals Origins of Bias in Visual Path Integration

The results suggest that visual path integration in noisy environments is limited largely by biases in processing optic flow rather than by leaky integration, which is better explained by a slow-speed prior than imperfect integration. Expand

Path integration in large-scale space and with novel geometries: Comparing vector addition and encoding-error models

- Medicine, Computer Science
- PLoS computational biology

A paradigm involving walking in an omnidirectional treadmill in which participants were guided on two sides of a triangle and then found their back way to origin was developed, suggesting the value of vector addition models in understanding these important components of human navigation. Expand

A subterranean mammal uses the magnetic compass for path integration.

- Proceedings of the National Academy of Sciences of the United States of America
- 2004

It is shown through two path integration experiments that the blind mole rat assesses direction both through internal signals and by estimating its heading in relation to the earth's magnetic field, and that the greater the circumvolution and length of the traveled path, the more the animal relies on the geomagnetic field.

The current literature on path integration and its interaction with external, location‐based cues is reviewed and special importance is given to the correlation between observable behavior and the activity pattern of particular neural cell populations that implement the internal representation of space.
