This study shows that androgen depletion in male mice increases sensitivity to effort costs and alters mesoaccumbal circuit function, with distinct effects depending on the timing of hormone loss.

The paper examines dendritic spine changes in mouse medial prefrontal cortex neurons during adolescence, finding greater remodeling in IT-type neurons and a role for microglia.

This study shows that requiring mice to perform a simple action to access high-fat diet reduces intake and prevents obesity, suggesting that easy access promotes overeating.

This study examines age and sex differences in pharmacokinetics and acute behavioral effects of vaporized cannabis extract in mice using different solvents.

This study shows that adolescent cannabis vapor use leads to lasting effects on behavior and brain structure in female rats, but not males, with higher self-administration rates in females.

This study investigates the role of the indirect pathway in choice suppression using chemogenetic manipulation in mice, finding that activation, not inhibition, of iSPNs disrupts suppression of nonrewarded choices.

This study shows that prepubertal ovariectomy in female mice alters decision-making strategies and DMS neuron excitability, affecting explore/exploit balance during reversal learning.

The paper examines how sex and pubertal status affect dendritic spine density in frontal corticostriatal projection neurons in mice, finding sex differences and pubertal regulation in spine pruning.

This paper introduces a non-genetically encoded near-infrared fluorescent nanosensor to image dopamine release in brain tissue with high spatial and temporal resolution.
