The simple act of picking up a cup of coffee requires the brain to perform a complex series of sensory to motor transformations. Specifically, the brain must use visual information to locate the cup, and visual and proprioceptive information (e.g. information derived from joint and limb angles) to locate the hand. This visual and proprioceptive information is then integrated and the brain decides on a plan for action. Intuitively, it makes sense for one to first form a conscious percept of the surrounding environment, including hand location, based on the incoming sensory information, and then to make this percept available to the parts of the brain that decide on plans for action. However, based on the visual experiences of some individuals, it is evident that the processing of visual information for perception and action does not take place in such a single or unified process. In fact, current models of sensory processing suggest that visual information (and proprioception) are processed along two anatomically distinct and functionally dissociated pathways, dependent on whether the information is to be used to guide action or for perception.

拿起一杯咖啡这个简单的动作需要大脑执行一系列复杂的感觉到运动的转换。 具体来说，大脑必须使用视觉信息来定位杯子，并使用视觉和本体感觉信息（例如从关节和肢体角度得出的信息）来定位手。 然后整合视觉和本体感觉信息，大脑决定行动计划。 直观地讲，人们首先根据传入的感官信息对周围环境（包括手的位置）形成有意识的感知，然后将这种感知提供给大脑中决定行动计划的部分。 然而，根据一些人的视觉经验，很明显，感知和行动的视觉信息处理并不是发生在这样一个单一或统一的过程中。 事实上，当前的感觉处理模型表明，视觉信息（和本体感觉）是沿着两条解剖学上不同且功能上分离的途径进行处理的，具体取决于信息是用于指导行动还是用于感知。
