Contrast enhancement in sensory systems often relies on spatial filters implemented by lateral inhibition. However, in this issue of Neuron, Fantana et al. provide evidence that lateral inhibition in the olfactory bulb selectively acts between sparse populations of principal neurons without regard to spatial relations.
感觉系统中的对比度增强通常依赖于由侧向抑制实现的空间滤波器。然而，在本期《神经元》杂志中，凡塔纳等人提供的证据表明，嗅球中的侧向抑制在主要神经元的稀疏群体之间选择性地起作用，而不考虑空间关系。
