Structural age-related reductions in baseline levels of DA may render the transient DA bursts insufficiently powerful to support incentive learning, whereas DA dips serve to amplify avoidance learning by depleting postsynaptic receptors from dopaminergic transmission even further. Thus, as compared with younger adults, who tend to be incentive learners, older adults tend to be avoidance learners, similar to Parkinson’s patients who suffer from striatal DA deficiencies and show deficient incentive learning and amplified avoidance learning. DA为多巴胺。 [ Last edited by gonga on 2011-6-21 at 07:38 ] |

| Structural age-related reductions in baseline levels of DA may render the transient DA bursts insufficiently powerful to support incentive learning, whereas DA dips serve to amplify avoidance learning by depleting postsynaptic receptors from dopaminergic transmission even further. 与年龄相关的结构性多巴胺基线水平下降致使支持激励学习的多巴胺释放不足，而多巴胺下降可通过更进一步从多巴胺能通路耗竭突触后受体而增强躲避性学习。Thus, as compared with younger adults, who tend to be incentive learners, older adults tend to be avoidance learners, similar to Parkinson’s patients who suffer from striatal DA deficiencies and show deficient incentive learning and amplified avoidance learning.因而，与通常为激励性学习者的年轻成人相比，老年人倾向为躲避性学习者，与纹状体多巴胺缺乏的帕金森氏症患者相似，显示激励性学习不足而躲避性学习增加。 |
