Rhythmicity in Mice Selected for Extremes in Stress Reactivity: Behavioural, Endocrine and Sleep Changes Resembling Endophenotypes of Major Depression
Figure 4
Diurnal variation of immunoreactive corticosterone metabolites (CM) in faecal samples of high (HR), intermediate (IR), and low (LR) reactivity males from generation VII over the 24-h light-dark cycle.
Data are given as means±SEM for each line. Statistical differences between the three lines are indicated by asterisks (KWH-tests, for details see text, p<0.05 *, p<0.01 **, p<0.001 ***). The dark phase of the light-dark cycle is indicated by the shaded area.
