研究人员利用功能性磁共振成像技术对大脑中活跃于产生通常（典型）或不寻常（非典型）名词-动词关系的区域进行了检查。7名成年人在对新名词和重复名词的反应中产生了第一个想到的动词（常用动词）（启动测试），然后产生了一个不寻常的动词或第一个想到的动词（不寻常测试）。左下前额叶皮层（LIPC）和右小脑在对新名词生成常用动词时比对重复名词生成常用动词时更活跃。当参与者产生不寻常的动词时，LIPC的激活没有增加，但右侧额中回和上级回，左侧额中回和双侧小脑的活动增加。结果支持的理论，右半球参与处理的遥远的协会，可能是有用的创造性思维和解决问题。
Brain areas active in generating usual (typical) or unusual (atypical) noun–verb relations were examined using functional magnetic resonance imaging. Seven adults generated the 1st verb to come to mind (usual verb) in response to novel and repeated nouns (priming test) and then generated either an unusual verb or the 1st verb to come to mind in response to novel nouns (unusual test). The left inferior prefrontal cortex (LIPC) and right cerebellum were more active when generating usual verbs to novel nouns than to repeated nouns. When participants generated unusual verbs, there was no increased activation in LIPC, but there was increased activity in the right middle and superior frontal gyri, left middle frontal gyrus, and bilateral cerebellum. Results support theories that the right hemisphere is involved in the processing of distant associations that may be useful in creative thought and problem solving.
