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.

This study shows chronic stress enhances task engagement in rats without impairing behavioral flexibility and reduces sex differences in lateral habenula activity during decision making.

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 examines how corticosterone affects sign- and goal-tracking behaviors in male and female rats from different vendors, finding sex- and vendor-dependent effects on acquisition but not expression.

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 how GluN2B antagonism affects extinction consolidation of methamphetamine-seeking behavior in adolescent vs. adult rats, finding no effect on extinction but sex differences in relapse.

This study shows that adolescent-onset methamphetamine self-administration in rats leads to increased drug intake and deficits in object-in-place recognition memory, with no changes in receptor expression.
