Lateral inhibition between near-neighbor neurons has long been thought to be important for narrowing the receptive fields of neurons in many sensory systems. A new study by Poo and Isaacson in this issue of Neuron examining olfactory processing finds that "global" inhibition within the primary olfactory cortex might accomplish a similar end.
长期以来，人们一直认为相邻神经元之间的侧向抑制对于缩小许多感觉系统中神经元的感受野很重要。蒲慕明和艾萨克森在本期《神经元》杂志上发表的一项关于嗅觉处理的新研究发现，初级嗅觉皮层内的“全局”抑制可能会达到类似的效果。
