Adolescent environmental enrichment induces social resilience and alters neural gene expression in a selectively bred rodent model with anxious phenotype

This study shows that adolescent environmental enrichment improves social resilience and alters gene expression in genetically anxious rats, with differential effects on behavior and stress response.

Bioenergetic-Related Gene Expression in the Hippocampus Predicts Internalizing vs. Externalizing Behavior in a F2 Cross of Selectively-Bred Rats

The paper identifies gene expression patterns in the hippocampus of rats that predict internalizing and externalizing behaviors, linking them to genetic variation and biological processes.

Perinatal fentanyl exposure leads to long-lasting impairments in somatosensory circuit function and behavior

This study shows that perinatal fentanyl exposure causes long-term impairments in somatosensory function and behavior in mice, with changes in synaptic and morphological properties.

Divergent profiles of fentanyl withdrawal and associated pain in mice and rats

This study compares fentanyl withdrawal and associated pain in mice and rats, finding species-specific differences in withdrawal symptoms and pain expression.

A neural system that represents the association of odors with rewarded outcomes and promotes behavioral engagement

The paper investigates how odor-reward associations are represented in brain regions and how these representations influence behavior during learning.
