Figure 5. Changes in sleep/wake architecture across postnatal development.

Figure 5

(A–C) Mean ± SEM vigilance state amounts as a % of total recording time (TRT) [P30 REM>P40-AD, AD vs. K31: p<0.05; NREM, all comparisons: ns; P30 wake < P40 & AD, K31 vs. AD: p<0.05]. (D–F) Mean ± SEM vigilance state durations in minutes [P30 REM < P35-AD & K31, K31 vs. AD; P30 NREM < P35-AD & K31, K31 vs. AD; P30 wake < P40 & AD: p<0.05]. (G–I) Mean ± SEM frequency of vigilance state episodes [P30 REM > P35-AD & K31; P30 NREM > all; P30 wake frequency > all: p<0.05]. Adult comparison data are indicated by “Ad”, P30–32 cat data by “K31”.
