Abstract
In this issue of Neuron, Mysore and Knudsen (2012) describe a simple, anatomically supported circuit that can categorize stimuli into "strongest" and "others," regardless of their absolute strength. Such flexible categorization cannot be achieved by lateral inhibition alone but also requires that the inhibitory neurons reciprocally inhibit each other.
摘要
在本期《神经元》杂志中，Mysore 和 Knudsen（2012）描述了一个简单的、具有解剖学支持的回路，它可以将刺激分为“最强”和“其他”，而不考虑它们的绝对强度。这种灵活的分类不能仅通过侧抑制来实现，还需要抑制性神经元相互抑制。
