Effects of ritanserin on differences in number of trajectories.

<p>Difference in number of trajectories was calculated by subtraction of ritanserin results from baseline vehicle measurements. In both groups the number of trajectories significantly decreases between wake and light SWS (LSWS) and vice versa after ritanserin (Rit) administration. Ritanserin significantly increased the number of trajectories of LSWS to deep SWS (DSWS) in UAO group. *<i>p</i><0.05 comparing ritanserin results to baseline vehicle measurements in the same animals. #<i>p</i><0.05 comparing change in trajectories between control and UAO groups.
