先前对前扣带皮层（ACC）的研究依赖于许多涉及认知控制和注意力需求的任务。在这项功能磁共振成像研究中，我们测试了 ACC 在语言处理中作为注意力网络发挥作用的模型。我们采用了一种范式，需要处理并发语言信息，预测竞争性试验所施加的认知成本将导致 ACC 的激活。受试者面临着语义内容与韵律语调冲突的句子（CONF 条件），并与传达连贯话语成分的句子（NOCONF 条件）随机间隔。我们观察到当从 CONF 条件中减去 NOCONF 条件时，头侧 ACC 和额中回的激活。我们的研究结果为 ACC 参与处理复杂的竞争性语言刺激提供了证据，支持了声称其作为皮质注意回路一部分的相关性的理论。情感韵律的处理涉及包含上颞叶皮质和内侧颞叶皮质的双边网络。这一证据证实了之前对支持情绪信息处理的神经元网络的研究。
Previous studies investigating the anterior cingulate cortex (ACC) have relied on a number of tasks which involved cognitive control and attentional demands. In this fMRI study, we tested the model that ACC functions as an attentional network in the processing of language. We employed a paradigm that requires the processing of concurrent linguistic information predicting that the cognitive costs imposed by competing trials would engender the activation of ACC. Subjects were confronted with sentences where the semantic content conflicted with the prosodic intonation (CONF condition) randomly interspaced with sentences which conveyed coherent discourse components (NOCONF condition). We observed the activation of the rostral ACC and the middle frontal gyrus when the NOCONF condition was subtracted from the CONF condition. Our findings provide evidence for the involvement of the rostral ACC in the processing of complex competing linguistic stimuli, supporting theories that claim its relevance as a part of the cortical attentional circuit. The processing of emotional prosody involved a bilateral network encompassing the superior and medial temporal cortices. This evidence confirms previous research investigating the neuronal network that supports the processing of emotional information.
