In vivo odourant response properties of migrating adult-born neurons in the mouse olfactory bulb

Juxtaglomerular neurons (JGNs) of the mammalian olfactory bulb are generated throughout life, but when and how these adult-born cells acquire responsiveness to sensory stimuli remains unknown. Here, the authors use in vivo two-photon imaging to monitor the migration and integration of adult-born JGNs and their sensory response properties.
