Abstract: Spatial working memory in an insect Visual orientation in a complex environment requires a memory for the positions of the various targets present in case they become temporarily out of sight. Vertebrates are equipped with this faculty, known as 'spatial working memory', a form of working memory that lasts at least for several seconds. Using a virtual-reality arena to present visual targets to walking flies, Neuser et al. show that insects also possess this faculty. Drosophila fruit flies lured away from a trip towards a hidden target remember the position of an object for several seconds after its removal. The neurons involved in the process are GABAergic ring neurons.
