Neurocomputational models of navigation

There are well established aspects of insect navigation, such as the use of vectors memories, which are well established, but we currently don’t have good models of how these behaviours might be implemented in the insect brain. Goldschmidt et al. address this with a model of Path Integration, where they extend the model to include the learning of vectors.

Abstract: “The model consists of a path integration mechanism, reward-modulated global learning, random search, and action selection. The path integration mechanism integrates compass and odometric cues to compute a vectorial representation of the agent’s current location as neural activity patterns in circular arrays. A reward-modulated learning rule enables the acquisition of vector memories by associating the local food reward with the path integration state. A motor output is computed based on the combination of vector memories and random exploration. “
