Abstract excerpt

Emerging evidence from animal studies suggests that suboptimal dopamine (DA) modulation may be associated with increased forgetting of episodic information. Extending these observations, we investigated the influence of DA-relevant genes on forgetting in samples of younger (n = 433, 20-31 years) and older (n = 690, 59-71 years) adults. The effects of single nucleotide polymorphisms of the DA D2 (DRD2) and D3...
