Abstract: In Drosophila, olfactory sensory neurons project to spatially invariant loci (glomeruli) and stereotyped circuitry is maintained in projections to a brain centre thought to mediate innate behaviours; here it is shown that neurons of the mushroom body, a centre that translates olfactory information into learned behaviours, integrate input from an apparently random combination of glomeruli, which could allow the fly to contextualize novel sensory experiences.
