The Central Complex as a Potential Substrate for Vector Based Navigation.

摘要: Insects use path integration (PI) to maintain a home vector, but can also store and recall vector-memories that take them from food location, even allow novel shortcuts between locations. The neural circuit of the Central Complex (a brain area receives compass optic flow information) forms plausible substrate for these behaviours. A recent model, grounded in neurophysiological neuroanatomical data, account PI during outbound exploratory routes control steering return home. Here, we show minor, hypothetical neurally plausible, extensions this model additionally explain how insects could vectors follow food-ward paths, shortcuts, search at feeder re-calibrate their with experience. In addition, simple assumption about one multiple might be chosen any point time produce development maintenance efficient locations, as observed bees. central complex circuitry is therefore well-suited rich vector-based navigational repertoire.
