Figure 6 Correlation analysis of these 25 lipids with behavioral phenotypic indices in mice. Correlation analysis of metabolites in the hippocampus (A), Correlation analysis of metabolites in the liver (B). Immobility time and the total distance are indicators of depression-like behavior in mice, and the numbers are correlation coefficients and the p values are shown with * and **.
