The threshold for intracranial self-stimulation does not increase in rats exposed to chronic unpredictable stress, a systematic review and meta-analysis

J. Berrio, J. Wilzopolski, K. Hohlbaum, O. Kalliokoski

This study reviews and analyzes 23 experiments to assess if chronic unpredictable stress increases intracranial self-stimulation thresholds in rats, finding no significant increase and no correlation with sweet preference.

Rethinking data treatment:The sucrose preference threshold for anhedonia in stress-induced rat models of depression

J. Berrio, O. Kalliokoski

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

Reliability of sucrose preference testing following short or no food and water deprivation - A Systematic Review and Meta-analysis of rat models of chronic unpredictable stress

J. P. Berrio, O. Kalliokoski, S. Hestehave

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.

Hair glucocorticoids are not a historical marker of stress - exploring the time-scale of corticosterone incorporation into hairs in a rat model

P. Colding-Jorgensen, S. Hestehave, K. S. Abelson, O. Kalliokoski

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

Are we overestimating the utility of hair glucocorticoids? A systematic review exploring the empirical evidence supporting hair glucocorticoids as a measure of stress

O. Kalliokoski, F. K. Jellestad, R. Murison

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.
