The cognitive control network (CCN) that comprises regions of the frontoparietal network, the cingulo-opercular network, and other sub-cortical regions as core structures is commonly activated by events with an increase in information uncertainty. However, it is not clear whether this CCN activation is associated with both information entropy that represents the information conveyed by the context formed by a sequence of events and the surprise that quantifies the information conveyed by a specific type of event in the context. We manipulated entropy and surprise in this functional magnetic resonance imaging study by varying the probability of occurrence of two types of events in both the visual and auditory modalities and measured brain response as a function of entropy and surprise. We found that activation in regions of the CCN increased as a function of entropy and surprise in both the visual and auditory tasks. The frontoparietal network and additional structures in the CCN mediated the relationship between these information measures and behavioral response. These results suggest that the CCN is a high-level modality-general neural entity for the control of the processing of information conveyed by both context and event.
认知控制网络（CCN）由额顶网络、扣带回-脑岛网络和其他皮质下区域的核心结构组成，通常在信息不确定性增加的事件中被激活。然而，目前尚不清楚这种 CCN 激活是否与信息熵和惊讶度都有关，信息熵代表由事件序列形成的上下文所传达的信息，而惊讶度则量化了上下文中特定类型事件所传达的信息。我们通过在视觉和听觉模态中改变两种类型事件的发生概率来操纵这两种信息的熵和惊讶度，并测量了大脑对熵和惊讶度的反应。我们发现，在视觉和听觉任务中，CCN 的区域激活随着熵和惊讶度的增加而增加。额顶网络和 CCN 中的其他结构介导了这些信息度量和行为反应之间的关系。这些结果表明，CCN 是一种高级的、模态通用的神经实体，用于控制由上下文和事件所传达的信息的处理。
