Change vector analysis (CVA) partitions spectral change into magnitude and direction components. Although recognized as an effective change detection method, CVA has two limitations. First, it is usually applied to only two bands, and secondly, the selection of a threshold for the magnitude of ...

Many behavioural tasks require the manipulation of mathematical vectors, but, outside of computational models1–7, it is not known how brains perform vector operations. Here we show how the Drosophila central complex, a region implicated in goal-directed
