The paper identifies QRFP/Pth4 neurons in zebrafish hypothalamus as a novel sleep-promoting population that acts through hindbrain monoaminergic neurons.

This study shows that early-life challenge in zebrafish larvae alters cortisol regulation and neuropeptide expression, enhancing stress reactivity after an initial suppression period.

This study examines cortisol responses in zebrafish larvae to repeated stress, revealing a rapid feedback loop and GR-dependent regulation, with implications for stress biology research.

This study investigates how varying acute stressor intensity affects social approach and maintenance in adult zebrafish, showing intensity-dependent reductions in both behaviors with social maintenance affected at lower stress levels.

The paper identifies three phenotypic subgroups of mice following chronic social defeat and finds brain-region specific transcriptional signatures associated with each subgroup.

This study investigates the lifelong molecular effects of high glucocorticoid exposure during development using a zebrafish model, identifying GC-primed genes and epigenetic changes linked to psychiatric disorder risk factors.

This study shows that elevated glucocorticoid exposure during zebrafish development disrupts hypothalamic neurogenesis, leading to developmental abnormalities and reduced survival.

This study uses optogenetics to chronically activate glucocorticoid signaling in larval zebrafish, showing impaired stress response and reduced POMC-expressing cells.

This study shows that oxytocin receptors influence the development and maintenance of social behavior in zebrafish, with effects varying by age and social context.

This study shows that the neuropeptide Pth2 in zebrafish affects anxiety and social behavior, with altered responses to stimuli and changes in social preference during development.
