Figure 3. LFP Spectral Power Decreases across Sleep and within REM Episodes and Increases within Non-REM Episodes.

Figure 3

For each session, pyramidal layer LFP spectra were normalized for each frequency bin as the Z score of non-REM power. (A) Spectral power decreases from the first to last non-REM episode of a sleep session across a wide range of frequencies (n = 22 sleep sessions). Shaded regions show 95% confidence intervals. Top black bars show frequencies for which sign-rank test was p < 0.05. (B) Spectral power changes within non-REM episodes (n = 82). (C) Spectral power changes within REM episodes (n = 45).
