利用功能磁共振成像技术研究类比推理过程中抽象相似关系的整合。激活引起的类比推理任务，需要复杂的工作记忆和抽象的类似关系的整合相比，激活引起的非类比任务，需要复杂的工作记忆中的抽象关系的整合。大脑额极的左侧区域（BA 9/10）选择性地活跃于类比推理的抽象关系整合部分。类比推理也涉及到左侧的顶额区域网络。在类比推理过程中，这个网络中的活动被假设为反映构成类比的各个组成部分的分类对齐。这种顶叶-额叶网络也参与了复杂的控制任务，这涉及明确的分类，但不是由一个简单的控制任务，这并不涉及分类。我们假设，额极皮层介导的抽象关系整合在复杂的推理，而顶叶-额叶区域介导的工作记忆过程，包括操纵的条款的目的，分类对齐，促进这种整合。(c)2006 Elsevier B.V.保留所有权利。
Integration of abstractly similar relations during analogical reasoning was investigated using functional magnetic resonance imaging. Activation elicited by an analogical reasoning task that required both complex working memory and integration of abstractly similar relations was compared to activation elicited by a non-analogical task that required complex working memory in the absence of abstract relational integration. A left-sided region of the frontal pole of the brain (BA 9/10) was selectively active for the abstract relational integration component of analogical reasoning. Analogical reasoning also engaged a left-sided network of parieto-frontal regions. Activity in this network during analogical reasoning is hypothesized to reflect categorical alignment of individual component terms that make up analogies. This parieto-frontal network was also engaged by the complex control task, which involved explicit categorization, but not by a simpler control task, which did not involve categorization. We hypothesize that frontopolar cortex mediates abstract relational integration in complex reasoning while parieto-frontal regions mediate working memory processes, including manipulation of terms for the purpose of categorical alignment, that facilitate this integration.
