This study examines the effect of preproenkephalin gene deletion on heart function in mice, finding no major changes in heart size or function under basal conditions but some reductions in filling and ejection rates.

This study shows that social reward in male mice decreases during mid-adolescence, mirroring human developmental patterns.

The paper shows that opioid receptor antagonists increase social conditioned place preference in early adolescent mice, suggesting developmental changes in social motivation mechanisms.

This study shows that adolescent mice show reduced reward sensitivity for social and food rewards but not cocaine, compared to adults, suggesting developmental changes in reward processing.
