Hierarchical cluster analyses of mouse single-unit ensembles in aPCX and pPCX to A, B, AB and A’B’. In aPCX, the component odors clustered closely with the elemental A’B’ mixture, while the configural AB mixture formed its own cluster, similar to that observed in the rat. In pPCX, while A’B’ and AB occupied distinct clusters, the association with the components was less clearly organized than in aPCX.
