Impact of exercise and housing conditions on behaviour at the EPM test. Behavioural measures in the EPM test for single-housed mice and pair-housed that either exercised or remained sedentary. a Percentage of time and b frequency performing stretch attend postures. Pearson’s correlation between time performing stretch attend postures and hippocampal expression of c Nr3c1 or d Nrc31-1 F. e Ratio time spent in the open arms versus all arms. f Frequency crossing into the open arms vs. all arms. g Distance moved. h Pearson’s correlation between distance moved in the EPM and daily distance run on the wheels. * p < 0.05 and ** p < 0.01
