Representative autoradiographic images of coronal brain sections with the corresponding bregma. Figure shows the in situ hybridization histochemistry of Per1 in the control group in the prefrontal cortex (PFC; the prelimbic part), nucleus accumbens (Acb), pineal gland (Pi), suprachiasmatic nucleus (SCN), substantia nigra (compacta part; SNc), ventral tegmental area (VTA), sub-regions of the hippocampus (CA1, CA3, and dentate gyrus [DG]), lateral habenula (LHb), and the basolateral part of the amygdala (BLA) at the time points indicated. Scale bar: applies to all images, 1mm.
