Table 1.

Mean repertoire similarities within and between units and individuals. Mantel test across all units has a null hypothesis that repertoire similarity between recordings of the same unit on different days (within unit) is the same as that between recordings of different units on different days (between units). Mantel tests among individuals within the three units have a null hypothesis that repertoire similarity between recordings of the same individual on different days (within individual) is the same as that between recordings of different individuals on different days (between individuals). Multivariate similarity using absolute ICIs, Euclidean distances and a basal similarity of 0.001. Categorical similarity using OPTICS classification.
