* = (CA1, CA3, and DG)
Peak and nadir of the control and anhedonic-like (anh.-like) rats for Per1, Per2, and Bmal1 clock genes in the pineal gland, suprachiasmatic nucleus, hippocampus, and liver. Peak and nadir are presented as zeitgeber time (ZT), where ZT 0 is defined as a time point when light in facilities is on.
– = no diurnal rhythm measured by two-way ANOVA.
