Attentional mechanisms in the posterior parietal cortex and the frontal eye fields have been studied in the rhesus monkey. In each of these areas single neurons discharge in response to visual stimuli and the discharge is enhanced when the monkey makes a saccade to the stimulus. In the posterior parietal cortex this enhancement also occurs whenever the monkey attends to the target, regardless of the movement or nonmovement that the monkey might make. Conversely, neurons in the frontal eye fields give enhanced responses only before saccades, and some discharge before purposive saccades made to remembered targets, with no overt current visual guidance. Some cells in the frontal eye fields also anticipate the onset of predictable saccades.
在恒河猴中，已经对后顶叶皮质和额叶眼区的注意力机制进行了研究。在这些区域中的每一个区域，单个神经元都会对视觉刺激产生放电反应，并且当猴子向刺激物进行扫视时，放电会增强。在后顶叶皮质中，无论猴子可能进行的运动或不运动，只要猴子关注目标，这种增强就会发生。相反，额叶眼区的神经元仅在扫视之前给出增强的反应，并且一些神经元在对记忆目标进行有目的的扫视之前放电，没有明显的当前视觉引导。额叶眼区的一些细胞也会预测可预测扫视的开始。
