Corrigendum: Circadian Chimeric Mice Reveal an Interplay Between the Suprachiasmatic Nucleus and Local Brain Clocks in the Control of Sleep and Memory

In the original article, there was an error in assignment of mouse strain identity.

A correction has been made to **Materials and Methods**, **Animals and housing**, **Paragraph number 1**:

All experiments were conducted in accordance with the UK Animals (Scientific Procedures) Act of 1986, with local ethical approval (MRC LMB, AWERB). Drd1a-Cre mice (Tg(Drd1-cre)EY266Gsat/Mmucd, RRID:MMRRC_030779-UCD) were purchased from the GENSAT project (Rockefeller University, New York, United States), through the Mutant Mouse Regional Resource Centers (MMRRC, United States). ROSA-YFP mice were provided by Dr. A. McKenzie (MRC LMB). Temporally chimeric mice were created by crossing Drd1a-Cre, ROSA26-EYFP mice with homozygotes for the floxed CK1ε Tau allele (Smyllie et al., 2016). All mice expressed the PER2::LUC bioluminescent reporter (Yoo et al., 2005) and had a C57/BL/6J background. This generated four genotypes: CRE-negative, CK1ε^WT/WT; CRE-positive, CK1ε^WT/WT; CRE-negative, CK1ε^Tau/Tau (Tau controls); CRE-positive, CK1ε^Tau/Tau (chimera). The first two groups were combined as WT, in light of no differences between them. Males aged 4–6 months old were used to avoid the estrous modulation of activity patterns.
