The data used here were obtained from the previous study by Lopes-dos-Santos et al. (2018) (20 (link)). Animals were male adult (4–7 months old) C57BL/6J mice (Charles River, UK) or transgenic heterozygous Cre-driver mice (Jackson Laboratories; obtained from C57BL/6J crossed with CamKIIa-Cre B6.Cg-Tg(Camk2a-cre)T29-1Stl/J, stock number 005359, RRID: IMSR_JAX:005359). All animals had free access to water and food in a dedicated housing facility with a 12-h light/12-h dark cycle (lights on at 7:00), 19–23 °C ambient temperature and 40–70% humidity. All mice were held in individually ventilated cages with wooden chew sticks and nestlets. The experimental procedures performed on these mice were conducted in accordance with the Animals (Scientific Procedures) Act, 1986 (United Kingdom), with final ethical review by the Animals in Science Regulation Unit of the UK Home Office.
