Animals can discriminate against very similar stimuli, but are also able to incorporate such stimuli into a learned group of stimuli and generalise a meaning. Different strategies have been implemented in the design of the neural circuit to achieve an optimum balance between stimuli discrimination and generalisation. Using connectomics analysis, computational modelling, and functional imaging, we investigate how the Drosophila mushroom body circuit provides the basis for this optimum balance.
