The sole input into our brain is sensory information. This information is processed, stored, and integrated in order to generate the brain's output - a behavioural response. Our five senses are constantly active, bombarding the brain with sensory information. In order to cope with this vast amount of information, different mechanisms are in place that filter out unimportant information and enable the brain to protect its resources for the processing of salient and potentially important input. One group of the sensory filtering mechanisms is called sensory gating. Sensory gating takes place in the central nervous system sensory pathways at an early stage of sensory information processing before information reaches consciousness. Two different neuronal mechanisms have been described that are built into the wiring of the brain in order to gate the information and thereby protect the brain from information overflow.

进入我们大脑的唯一输入是感官信息。这些信息被处理、存储和整合，以产生大脑的输出--一种行为反应。我们的五种感官持续活跃，用感官信息轰炸大脑。为了处理这些海量的信息，有不同的机制可以过滤掉不重要的信息，使大脑能够保护其资源，以处理重要的和潜在的重要输入。其中一组感觉过滤机制被称为感觉门控。感觉门控在信息到达意识之前的感觉信息处理的早期阶段发生在中枢神经系统的感觉通路中。已经描述了两种不同的神经机制，它们内置在大脑的连线中，以控制信息，从而保护大脑免受信息溢出的影响。
