功能解剖学和单单位记录研究表明，顶叶和额叶皮层中的一组神经信号介导了注意力对视觉位置的隐蔽分配，正如最初由心理学研究提出的那样，这个额顶叶网络是位置偏差的来源，它在物体分析期间与腹侧视觉系统的纹外区域相互作用以增强视觉处理，额顶叶网络并不完全与视觉注意相关，但可能与眼动过程中涉及的区域重合或重叠，在心理学，功能解剖学和细胞水平的分析中讨论了注意和眼动过程之间的关系。
Functional anatomical and single-unit recording studies indicate that a set of neural signals in parietal and frontal cortex mediates the covert allocation of attention to visual locations, as originally proposed by psychological studies, This frontoparietal network is the source of a location bias that interacts with extrastriate regions of the ventral visual system during object analysis to enhance visual processing, The frontoparietal network is not exclusively related to visual attention, but may coincide or overlap with regions involved in oculomotor processing, The relationship between attention and eye movement processes is discussed at the psychological, functional anatomical, and cellular level of analysis.
