Division of labor for division: Inhibitory interneurons with different spatial landscapes in the olfactory system

摘要

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 etal. (2013) and Miyamichi etal. (2013), suggest that parvalbumin-positive interneurons in the olfactory bulb play a role in this process.
