	OX2R WT	OX2R KO	OX2R WT	OX2R KO
1–2 h	63.1 ± 4.6	58.7 ± 3.4	6.5 ± 1.0	5.8 ± 1.3
3–4 h	72.5 ± 3.6	72.3 ± 4.2	8.7 ± 1.0	7.5 ± 0.8
5–6 h	75.0 ± 2.4	74.6 ± 2.2	11.6 ± 1.2	9.5 ± 1.0
7–8 h	78.4 ± 2.9	73.8 ± 2.4	10.6 ± 1.2	8.9 ± 0.7
9–10 h	72.4 ± 3.2	69.3 ± 2.5	9.4 ± 1.1	8.6 ± 0.5
11–12 h	69.9 ± 3.5	67.5 ± 1.4	8.6 ± 1.1	8.6 ± 0.6

Mean (± SEM) values (n = 10 OX2R WT, n = 10 OX2R KO) are determined per 2-h intervals and are expressed in minutes.
