In larval zebrafish, 68% of 81 traced serotonergic dorsal raphe neurons target only one of telencephalon and spinal cord; stress in week 1, not week 2, raised telencephalic fiber density.

This study shows that stress intensity determines serotonergic involvement in anxiety, with higher stress leading to DRN-independent anxiety and dopaminergic modulation.

This study shows that early life chronic stress disrupts DRN serotonergic activity, particularly in vulnerable GABAergic cells, leading to specific behavioral impairments.

The paper identifies pretrauma cognitive traits predicting trauma-induced fear generalization and prefrontal cortex changes in a rat model of PTSD.

This study compares the behavioral responses of paradise fish and zebrafish in social and non-social tasks, finding that paradise fish show less social bias and more consistent behavior in individual-based assays.

This study identifies KCNQ3 as a genetic risk factor for fear-related behaviors in dogs and zebrafish, showing gene-environment interactions influence freezing behavior.

This paper introduces a validated test battery to measure trait anxiety in rodents by combining multiple behavioral tests and using summary measures to improve predictive validity and molecular correlate identification.

This study shows that early-life social isolation in zebrafish alters serotonergic signaling and behavioral responsiveness to challenges, with pharmacological intervention rescuing these effects.
