我们用脑磁图跟踪了5名正常成年人在成功学习陌生物体的名称和/或意义时与命名相关的皮层动力学的演变。在所有受试者中，新名字的学习与明显的皮质效应有关。学习效应具有长潜伏期，表现为在熟悉的项目命名过程中激活的同一皮层网络的激活变化。在五名受试者中，有四名受试者的皮层学习效应发生在下顶叶。在其中三个受试者中，皮质效应是左侧的。这些结果表明，下顶叶在新词语的习得中起着重要的作用，可能是工作记忆系统的一部分。(C)2004年爱思唯尔公司All rights reserved.
We tracked the evolvement of naming-related cortical dynamics with magnetoencephalography when five normal adults successfully learned names and/or meanings of unfamiliar objects. In all subjects, the learning of new names was associated with pronounced cortical effects. The learning effect was of long latency and emerged as a change of activation in the same cortical network that was active during naming of familiar items. In four out of five subjects, the cortical learning effect occurred in the inferior parietal lobe. In three of these subjects, the cortical effect was left-sided. These results suggest that the inferior parietal lobe plays an important role in the acquisition of novel words, presumably as a part of working memory systems. (C) 2004 Elsevier Inc.
