A. The 3353 Da sleep peak. Left, spectra for 6 representative rats for 3 groups (S; S-SD, W; H50 arrays; same intensity scale for all spectra). Right, scatter plots for all animals in the 3 groups (H50 arrays). B. The 15206 Da waking peak. Left, spectra for 6 representative rats for 3 groups (S, S-SD, W; CM10 arrays; same intensity scale for all spectra). Right, scatter plots for all animals in the 5 groups (CM10 arrays). C. The 12103 Da peak increased with long sleep deprivation. Left, spectra for 4 representative rats for each group (S-SD, L-SD, SR, W; CM10 arrays; same intensity scale for all spectra). Right, scatter plots for all animals (CM10 arrays).
