This study shows that high SPS-like rats have increased cocaine self-administration and altered glutamatergic/GABAergic signaling in the prefrontal cortex, suggesting a risk factor for cocaine use disorder.

This study compares reward sensitivity to ethanol and sucrose in DAT and SERT knockout rats, finding DAT deletions broadly impair both rewards while SERT deletions selectively affect sucrose.

This study investigates the effect of serotonin transporter gene knockout on decisional anhedonia in rats, finding mild modulation that interacts with learning.

This study shows cocaine increases extracellular dopamine and serotonin by depleting storage vesicles in the rat nucleus accumbens, with individual differences in vesicular release affecting behavior and drug intake.
