From: Metabolomics of mammalian brain reveals regional differences
Multivariate analysis via PCA reduces the complexity of the brain region metabolome and identifies key components that contribute to their differences. a. Scattered scores plot shows the degree of separation across all brain region samples when metabolites with real significance are analyzed. b. Scattered loadings plot highlights the category of metabolites that contribute to the separation of the brain region clusters. c-d. The top 10 metabolites that explain the metabolome differences of the brain regions based on principal components 1 and 2. OB, olfactory bulb; FCX, frontal cortex; HC, hippocampus; CBL, cerebellum
