Länk - Neuroner som skapas och vandrar i den vuxna hjärnan
In rats and mice, a structure called the rostral extension connects the lateral ventricles and the olfactory bulb. This tube-like structure, which is filled with cerebrospinal fluid, provides a pathway for neurons generated in the subventricular zone (a proliferative tissue lining the cerebral ventricles) to migrate to the olfactory bulb, which contains neurons that bind to odorant receptors and produce nervous impulses related to smell. The rostral migratory stream is the equivalent of the rostral extension in rodents, and was not known to exist in humans before this study.
