Which co-ordinate scheme for path integration?

A persistent question in navigation research concerns the internal encoding system that insects use for path integration. Rob Vickerstaff explains below why he is interested in this particular question.

“While analysing my evolved model path integration (PI) system (doi:10.1242/jeb.01772), I noticed that its behaviour was often easier to understand from the perspective of a different reference frame than the model’s ‘nervous system’ actually used internally. Why not systematically examine all aspects of the model from all possible reference frames? This lead to my recent JTB paper (doi:10.1016/j.jtbi.2009.11.021) with Allen Cheung where we use a classification scheme of his to suggest that one class of spatial representation is best for biological PI. The results also show how difficult it is to deduce which representation is being used by the nervous system from behavioural data alone. Our forth coming paper (Cheung&Vickerstaff,submitted) shows the same spatial representation class is the only one robust to the effects of neural noise – we conclude that this class of representation is likely to be used by all biological PI systems operating over significant distances.” – Robert Vickerstaff
