通过2个大鼠实验，研究了杏仁核中央核（CN）神经毒性损伤对食欲巴甫洛夫条件反射中CS关联能力变化的影响。在实验1中，CN病变对预暴露于该线索（潜伏抑制）产生的CS的关联性降低没有影响。在实验2中，当CS与另一个线索之间存在不一致的预测关系时，通常会观察到，CN病变阻止了CS关联性的增强。结果支持先前的说法，即杏仁核CN参与巴甫洛夫条件反射中CSs加工的广泛增量变化，而不是递减变化。（PsycINFO数据库记录(c) 2016 APA，版权所有）
The effects of neurotoxic lesions of the amygdala central nucleus (CN) on changes in the associability of a CS in appetitive Pavlovian conditioning were examined in 2 experiments with rats. In Exp 1, CN lesions had no effect on the reduction in the associability of a CS produced by preexposure to that cue (latent inhibition). In Exp 2, CN lesions prevented the enhancement of the associability of a CS that is normally observed when an inconsistent predictive relation is arranged between that CS and another cue. Results support previous claims that the amygdala CN is involved in broad-based incremental, but not decremental, changes in the processing of CSs in Pavlovian conditioning.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
