The dorsal attentional network is known for its role in directing top-down visual attention toward task-relevant stimuli. This goal-directed nature of the dorsal network makes it a suitable candidate for processing and extracting predictive information from the visual environment. In this review we briefly summarize some of the findings that delineate the neural substrates that contribute to predictive learning at both levels within the dorsal attentional system: including the frontal eye field (FEF) and posterior parietal cortex (PPC). We also discuss the similarities and differences between these two regions when it comes to learning predictive information. The current findings from the literature suggest that the FEFs may be more involved in top-down spatial attention, whereas the parietal cortex is involved in processing task-relevant attentional influences driven by stimulus salience, both contribute to the processing of predictive cues at different time points.
背侧注意网络以其在将自上而下的视觉注意引导至与任务相关的刺激的作用而闻名。 该背侧网络的目标导向性质使其成为从视觉环境中处理和提取预测信息的合适候选者。 在这篇综述中，我们简要总结了一些发现，这些发现描绘了有助于在背侧注意系统内的两个水平上进行预测学习的神经基质：包括额眼场（FEF）和顶后皮质（PPC）。 我们还讨论了当涉及到学习预测信息时，这两个区域之间的相似之处和不同之处。 目前的文献研究结果表明，FEF 可能更多地参与自上而下的空间注意，而顶后皮质则参与由刺激显着性驱动的与任务相关的注意力影响的处理，两者都有助于在不同时间点处理预测线索。
