Neuronal mechanisms underlying gating of sensory information

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。我们的五种感官一直处于活跃状态，用感官信息轰击大脑。为了处理大量的信息，不同的机制可以过滤掉不重要的信息，并使大脑能够保护其资源，以处理突出的和潜在的重要输入。一组感觉过滤机制被称为感觉门控。感觉门控发生在感觉信息加工的早期阶段，即信息到达意识之前，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元机制，它们内置于大脑的线路中，以控制信息，从而保护大脑免受信息溢出。

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.
