Percent time spent in wake (W), REM sleep (RS) and slow-wave-sleep (SWS) in the 8 h recording period in OR (A, OR) and Sprague-Dawley (B, SD) rats. Percent change in W, RS and SWS from baseline in OR and SD rats (C). During partial sleep deprivation (PSD), both groups of rats spent more time in W and less time in SWS and RS. Results are expressed as percent of total recording time, and represented as mean ± S.E.M. N=6/group. **P < 0.01, ***P < 0.001 as compared to respective controls. πP < 0.05 as compared to W in SD rats during control recording conditions.
