The effect of preproenkephalin gene deletion on heart function in mice

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.

Changes in social reward across adolescence in male mice

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

Mu and delta opioid receptor antagonists increase the expression of social conditioned place preference in early adolescent mice

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

Decreased social, drug, and food reward sensitivity in adolescent mice

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.

L-DOPA induces spatially discrete changes in gene expression in the forebrain of mice with a progressive loss of dopaminergic neurons

The paper examines L-DOPA-induced gene expression changes in the forebrain of mice with progressive dopaminergic neuron loss, identifying region-specific effects and novel genes involved in nonmotor PD symptoms.

μ-Opioid receptor transcriptional variants in the murine forebrain and spinal cord

The paper identifies a long 3' untranslated region in the primary Oprm1 transcript in mice, with additional variants expressed at lower levels.

Generalized habitual tendencies in alcohol dependent rats

This study shows that alcohol-dependent rats show increased habitual behavior towards a sweet reward in two tasks, and DMS inactivation in non-dependent rats also increases habitual behavior.
