The methodologies of cognitive architectures and functional magnetic resonance imaging can mutually inform each other. For example, four modules of the ACT-R (adaptive control of thought - rational) cognitive architecture have been associated with four brain regions that are active in complex tasks. Activity in a lateral inferior prefrontal region reflects retrieval of information in a declarative module; activity in a posterior parietal region reflects changes to problem representations in an imaginal module; activity in the anterior cingulate cortex reflects the updates of control information in a goal module; and activity in the caudate nucleus reflects execution of productions in a procedural module. Differential patterns of activation in such central regions can reveal the time course of different components of complex cognition.
认知架构方法与功能磁共振成像能够相互提供信息。例如，ACT-R（思维的自适应控制-理性）认知架构的四个模块已与在复杂任务中活跃的四个脑区相关联。外侧下前额叶区域的活动反映了陈述性模块中信息的检索；顶叶后部区域的活动反映了想象模块中问题表征的变化；前扣带回皮质的活动反映了目标模块中控制信息的更新；尾状核的活动反映了程序模块中产生式的执行。这些中枢区域不同的激活模式能够揭示复杂认知不同组成部分的时间进程。
