Adult-born neurons in the olfactory bulb allow state-dependent pattern separation of representations of similar odorants.

Inhibitory circuits in the olfactory bulb can amplify or suppress sensory inputs over a wide range of intensities to generate robust mitral cell output.

Adult neurogenesis in the olfactory bulb is not a turnover system but represents a lifelong neuronal addition mechanism.

During adult neurogenesis in the olfactory bulb, microglia regulate the elimination (pruning), formation, and maintenance of synapses on newborn neurons, contributing to the functional integrity of the olfactory bulb circuitry.

Distinct lateral inhibitory circuits affect spiking in olfactory bulb mitral and tufted cells differently, which ultimately allows each cell type to best discriminate between similar odors in separate concentration ranges.

Sister projection neurons in the mammalian olfactory system do not share sensory synaptic input indicating that lineage-independent mechanisms regulate their synaptic connectivity with the olfactory sensory neurons.

Sensory representation in the primary olfactory area is rapidly modulated when mice switch between easy and difficult discrimination tasks, optimising the sensory representation for the task at hand.

While both implicit and explicit learning augment neurogenesis, adult-born cells differ in their morphology, functional coupling and inhibitory action impacting differentially the olfactory bulb output.

In the mouse olfactory bulb, different types of local dopaminergic interneuron are produced before and after birth.
