Distant brain regions selectively recruit stem cells

Via Top Health News -- ScienceDaily

Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group reports that long-distance brain connections can target discrete pools of stem cells in their niche and stimulate them to divide and produce specific subtypes of olfactory bulb neurons. This allows the 'on-demand' generation of particular types of neurons in the adult brain.
