Jonasson et al. investigated whether individual differences in human dopamine receptors (D2R) were related to cognitive performance before and after a 6-month aerobic exercise intervention (compared with active control). While D2R decreased (perhaps counterintuitively) with exercise, there was no relationship between D2R and working memory at baseline or following exercise.

老年人的运动、多巴胺和认知

乔纳森等人。研究了人类多巴胺受体 (D2R) 的个体差异是否与 6 个月有氧运动干预前后的认知表现有关（与主动控制相比）。虽然 D2R 会随着运动而降低（可能违反直觉），但 D2R 与基线或运动后的工作记忆之间没有关系。
