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.

拿一杯咖啡的简单行为要求大脑对运动转换进行一系列复杂的感觉。 具体而言，大脑必须使用视觉信息来定位杯子，以及视觉和本体感受信息（例如，从关节和肢体角度得出的信息）来定位手。 然后集成了此视觉和本体感受信息，大脑决定采取行动计划。 直观地，首先根据传入的感官信息来形成对周围环境（包括手位置）的有意识的感知，然后使这一感知可用于决定采取行动计划的大脑部分，这是有意义的。 但是，根据某些人的视觉经历，很明显，在这种单一或统一的过程中，视觉信息的处理不会发生。 实际上，当前的感觉处理模型表明，视觉信息（和本体感受）沿两个解剖学上不同且功能分离的途径进行处理，取决于是否要使用信息来指导动作还是进行感知。
