Fig. 2. Inhibition of KYNA synthesis at the beginning of light phase promotes REM and NREM sleep and reduces wakefulness in ECon and EKyn offspring.

Adult ECon and EKyn offspring were treated with vehicle or PF-04859989 (30 mg/kg) at Zeitgeber time (ZT) 0. A 1-h bins of REM duration in male and female ECon (three-way ANOVA: treatment effect F(1, 13) = 10.00, P < 0.01; Two-way ANOVA: Male Treatment effect F(1, 7) = 8.938, P < 0.05). B 1-h bins of REM duration in male and female EKyn (three-way ANOVA: Treatment effect F(1, 14) = 11.76, P < 0.01; two-way ANOVA: male treatment effect F(1, 7) = 7.211, P < 0.05). C 6-h bins of REM duration in ECon, sexes combined (Treatment effect F(1, 14) = 10.22, P < 0.01). D 6-h bins of REM duration in EKyn, sexes combined (Treatment effect F(1, 15) = 11.15, P < 0.01).
