摘要

我们将动态因果模型应用于两只猕猴执行一项涉及工作记忆的解决问题任务的皮质电图记录,并诱导了任务时间效应。因此,我们提供了在额顶叶网络的两个区域,背外侧前额叶皮层和前补充运动区域内有效连接变化的计算帐户。我们发现,当任务要求增加时,两个区域之间的正向连接的强度增加,随着实验的进行。任务需求和时间对任务的影响的相似性使我们能够从增加的注意力努力分配来补偿认知疲劳的角度来解释额叶连接的变化。

Frontal effective connectivity increases with task demands and time on task: a Dynamic Causal Model of electrocorticogram in macaque monkeys
We apply Dynamic Causal Models to electrocorticogram recordings from two macaque monkeys performing a problem-solving task that engages working memory, and induces time-on-task effects. We thus provide a computational account of changes in effective connectivity within two regions of the fronto-parietal network, the dorsolateral prefrontal cortex and the pre-supplementary motor area. We find that forward connections between the two regions increased in strength when task demands increased, and as the experimental session progressed. Similarities in the effects of task demands and time on task allow us to interpret changes in frontal connectivity in terms of increased attentional effort allocation that compensates cognitive fatigue.
