Olfactory bulb mitral and tufted cells are thought to be particularly active at rest and to respond weakly to odors during wakefulness. By using blind, whole cell recordings in awake mice, Kollo and colleagues now reveal the existence of a previously overlooked subpopulation of mitral/tufted cells that are silent at rest but respond greatly to odors.
