多项证据表明，规划眼球运动和引导视觉空间注意力具有重叠的大脑机制。这项研究测试了是否可以通过改变大脑内的动眼神经信号来增强空间注意力。猴子执行空间注意力任务，同时额眼区（前额皮质内的动眼区域）内的神经元受到低于引起眼球运动水平的电刺激。我们发现，当但仅当要关注的物体位于皮质刺激部位所代表的空间中时，我们可以通过微刺激来提高猴子的表现。
Several lines of evidence suggest that planning eye movements and directing visuospatial attention share overlapping brain mechanisms. This study tested whether spatial attention can be enhanced by altering oculomotor signals within the brain. Monkeys performed a spatial attention task while neurons within the frontal eye field, an oculomotor area within prefrontal cortex, were electrically stimulated below the level at which eye movements are evoked. We found that we could improve the monkey's performance with microstimulation when, but only when, the object to be attended was positioned in the space represented by the cortical stimulation site.
