多年来,关于顶叶在行为产生中的作用一直存在争议。它是否生成移动计划(意图)或选择环境中的对象进行进一步处理?为了回答这个问题,我们专注于外侧顶内区(LIP),该区域已被证明在眼跳的目标选择和视觉注意的产生中发挥独立的作用。基于从各种任务的结果,我们建议,LIP作为一个优先级地图中的对象表示的活动成比例的行为优先级。我们提出的证据表明,优先级地图相结合的自下而上的输入,如快速的视觉反应与一系列自上而下的信号,如扫视计划。表示图的峰值的空间位置由眼视系统使用以瞄准扫视,并且由视觉系统使用以引导视觉注意。
For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention.
