  1. Pairwise correlation matrix of orexin fiber distribution in the Long-Evans rat, grass rat, Syrian hamster, and degu. Correlation values were obtained from a principal component factor analysis of orexin A and orexin B fiber density patterns in all four species. Values listed at intersections between rows and columns represent the correlation in fiber density between species indicated by the corresponding row and column labels. All values represent significant correlations (p < 0.001).
