Functional magnetic resonance imaging (fMRI) and surface-based representations of brain activity were used to compare the functional anatomy of two tasks, one involving covert shifts of attention to peripheral visual stimuli, the other involving both attentional and saccadic shifts to the same stimuli. Overlapping regional networks in parietal, frontal, and temporal lobes were active in both tasks. This anatomical overlap is consistent with the hypothesis that attentional and oculomotor processes are tightly integrated at the neural level.
功能磁共振成像(fMRI)和基于表面的大脑活动表征被用于比较两项任务的功能解剖结构,一项任务涉及对周边视觉刺激的注意力隐蔽转移,另一项任务涉及对相同刺激的注意力和眼跳转移。顶叶、额叶和颞叶中重叠的区域网络在两项任务中均活跃。这种解剖学上的重叠与注意力和眼球运动过程在神经水平上紧密整合的假设一致。
