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.

Enriched environment stimulates neuron generation in the hippocampus by a novel pathway involving Agrin, Lrp4, and Ror2.

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

Adult neurogenesis, although happening at a slow rate in the adult brain, plays an important role in learning and memory and has the ability to powerfully modulate large scale neural networks.

Planarian brain neurons modulate their turnover by signaling to nearby stem cells.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

Control of neural stem cells by reactive oxygen species (ROS) provides a link between systemic shifts in oxygen tension and neuronal regeneration, and suggests an evolutionary driving force for the inherent ability of newts to regenerate their brain cells.

In adult mouse hippocampus, neural stem cell and their progeny communicate via Lunatic Fringe mediated Notch signaling to regulate stem cell quiescence, division, and fate.

3-10 weeks old adult-born granule cells provide two temporally overlapping but functionally distinct neuronal cell populations by being sensitive to distinct aspects of their inputs.

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