From: Metabolic fingerprints of fear memory consolidation during sleep
Changes in purine metabolism during sleep–wake state transitions and fear memory consolidation. a Fold changes of each metabolite in the purine metabolic pathway (e.g., REM/Wake indicates REM vs. Wake). Bars, mean; error bars, 95% CI; *p < 0.05, **p < 0.01 regardless of fold change; N.D., no data available. b Summary of results in a. Large arrows (color-coded as in a) indicate increases (pointing upward) or decreases (pointing downward) in the amount of each metabolite
