Fig. 9From: The fusion of multi-omics profile and multimodal EEG data contributes to the personalized diagnostic strategy for neurocognitive disordersEvaluation of metagenomic analysis of gut microbiota and metabolomic analysis of serum and hippocampus in faecal microbiota transplantation (FMT) mice. A Stacked bar chart illustrated the relative and average relative abundance of gut microbiota at the phylum level at different time points: days 0, 14, 21, and 38 (T1, T2, T3, and T4). B Principal component analysis (PCA) of gut microbiota composition suggested the distances at T1, T2, T3, and T4. C Alpha diversity analysis of gut microbiota at the species level, as determined by Chao1 index, Shannon index, and Simpson index. D Venn diagram showed the gut microbiota species present. E The changes in relative abundance of signature gut microbiota species of seniors with NCDs in FMT mice. F Heat maps and variable importance plots of serum metabolites. G Heat maps and variable importance plots of hippocampus metabolites. The row dendrograms were generated using hierarchical clustering with the Euclidean distance metricBack to article page
