Normalizing neural responses by the sum of population activity allows the nervous system to adjust its sensitivity according to task demands, facilitating intensity-invariant information processing. In this issue of Neuron, two studies, Kato et al. (2013) and Miyamichi et al. (2013), suggest that parvalbumin-positive interneurons in the olfactory bulb play a role in this process.
通过群体活动的总和来规范神经反应，使神经系统能够根据任务需求调整其灵敏度，促进强度不变的信息处理。在本期《神经元》杂志上，两项研究，Kato 等人（2013 年）和 Miyamichi 等人（2013 年），表明嗅球中的 PV 阳性中间神经元在这个过程中发挥了作用。
