This paper critiques the use of arbitrary thresholds in defining anhedonia in stress-induced rat models, showing how such thresholds introduce statistical bias.

This paper reviews the development of home cage monitoring in mice and rats, showing increased use of automation and expanded behavioral and physiological parameters over time.

This study evaluates the reliability of the sucrose preference test in rat models of chronic unpredictable stress, finding that short or no fasting improves reliability and that metabolic factors confound results.

This study shows hair glucocorticoids reflect recent stress, not historical stress, by tracking corticosterone uptake in rats over seven days.

This paper reviews evidence for hair glucocorticoids as a stress biomarker, finding support for their correlation with stress but no proof they measure historical stress.
