Neurogenesis continues well beyond embryonic and early postnatal ages in three areas of
the nervous system. The subgranular zone supplies new neurons to the dentate gyrus of the …

Olfactory sensory neurons (OSNs) in the olfactory epithelium of the nose transduce chemical
odorant stimuli into electrical signals. These signals are then sent to the OSNs' target …

In humans, discrimination between individuals, also termed social recognition, can rely on a
single sensory modality, such as vision. By analogy, social recognition in rodents is thought …

The mouse olfactory system regenerates constantly throughout life. While genes critical for
the initial projection of olfactory sensory neurons (OSNs) to the olfactory bulb have been …

Lifelong neurogenesis endows the mouse olfactory system with a capacity for regeneration
that is unique in the mammalian nervous system. Throughout life, olfactory sensory neurons …

Postnatal neurogenesis provides an opportunity to understand how newborn neurons
integrate into circuits to restore function. Newborn olfactory sensory neurons (OSNs) wire …

Successful neuronal regeneration requires the reestablishment of synaptic connectivity. This
process requires the reconstitution of presynaptic neurotransmitter release, which we …

The olfactory system has a unique capacity for recovery from peripheral damage. After injury
to the olfactory epithelium (OE), olfactory sensory neurons (OSNs) regenerate and re …

Highlights•Odors are important signs of threats and resources.•Odor valence is coded in the
brain.•Specific areas code valence already in olfactory bulb and antennal lobe.•Coding of …

The perception of odours is the result of the complex processing of a signal, which initiates
at peripheral receptors and ends in the brain. Along this pathway, olfactory signal …
