There must be a sensory filtering system, and it is this filtering system that is important in understanding pain perception. It helps to explain why pain can vary enormously from one situation to another for a single individual. For example, many of us have noticed bruises from a ball game and do not remember how they were obtained. Yet, at other times seemingly innocuous stimuli, suchas stubbing a toe, can be perceived as excruciating. Same patients react differently. These differences can be explained by a filtering mechanism.
