采用高密度事件相关脑电位（ERPs）研究了简单类比（EA）和困难类比（DA）任务执行过程中脑激活的时空变化。结果表明，推理任务（图式归纳）引起了更多的负ERP偏转（N500-1000）比基线任务（BS）之间的500和1000 ms。偶极子源分析的差异波（EA-BS和DA-BS）表明，负成分都定位于左丘脑附近，可能与检索的字母信息。在同一时间窗内，DA诱发的ERP成分（P600-1000）明显高于EA。P600-1000的两个发生器位于内侧前额叶皮层（BA 10）和左额叶皮层（BA 6），可能参与图式提取中的信息整合。在类比映射阶段，额中央头皮区域的负性（N400-600）比BS更大。这种效应的发生器位于左侧梭状回，可能与联想记忆和图式激活有关。在推理任务中，与BS任务相比，在900-1200 ms（LNC 1）和2000-2500 ms（LNC 2）之间产生了更大的负性。偶极源分析（EA-BS）将LNC 1的发生器定位在左前额叶皮层（BA 10），这可能与将图式映射到目标问题有关，而LNC 2的发生器定位在左前额叶皮层（BA 9），这可能与决定结论是否正确地从图式中得出有关。(C)2008爱思唯尔有限公司保留所有权利。
The spatiotemporal analysis of brain activation during the execution of easy analogy (EA) and difficult analogy (DA) tasks was investigated using high-density event-related brain potentials (ERPs). Results showed that reasoning tasks (schema induction) elicited a more negative ERP deflection (N500-1000) than did the baseline task (BS) between 500 and 1000 ms. Dipole source analysis of difference waves (EA-BS and DA-BS) indicated that the negative components were both localized near the left thalamus, possibly associated with the retrieval of alphabetical information. Furthermore, DA elicited more positive ERP component (P600-1000) than did EA in the same time window. Two generators of P600-1000 were located in the medial prefrontal cortex (BA10) and the left frontal cortex (BA6)which was possibly involved in integrating information in schema abstraction. In the stage of analogy mapping, a greater negativity (N400-600) in the reasoning tasks as compared to BS was found over fronto-central scalp regions. A generator of this effect was located in the left fusiform gyrus and was possibly related to associative memory and activation of schema. Then, a greater negativity in the reasoning tasks, in comparison to BS task, developed between 900-1200 ms (LNC1) and 2000-2500 ms (LNC2). Dipole source analysis (EA-BS) localized the generator of LNC1 in the left prefrontal cortex (BA 10) which was possibly related to mapping the schema to the target problem, and the generator of LNC2 in the left prefrontal cortex (BA 9) which was possibly related to deciding whether a conclusion Correctly follows from the schema.
