Fig. 1

The hierarchical clustering plot of differentially expressed circRNAs (fold change ≥1.5, p < 0.05). Red indicates circRNAs with high expression levels, and green represents circRNAs with low expression levels, the color depth (ranging from black to color) indicates different expression intensities. Each row in the figure indicates a different circRNA, and each column indicates a sample (T is the ketamine group and C is the vehicle group). The left side of the figure shows the circRNA clustering tree, whereas the top shows the hippocampal sample clustering tree
