Lipid metabolism regulates the activity of adult neural stem cells
(Medical Xpress)—Neural stem cells in the adult brain boost their levels of lipid metabolism to grow and generate new neurons. This new finding may open novel therapeutic avenues to treat age- or disease-associated ...

Major discovery explains how adult brain cleans out dead brain cells, produces new ones
(Medical Xpress) -- Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, ...

Neurogenesis
Neurogenesis (birth of neurons) is the process by which neurons are generated from neural stem and progenitor cells. Most active during pre-natal development, neurogenesis is responsible for populating the growing brain with neurons. Recently neurogenesis was shown to continue in several small parts of the brain of mammals: the hippocampus and the subventricular zone. Studies have indicated that hormones, such as testosterone in vertebrates and ecdysone in invertebrates, have an influence on the rate of neurogenesis.
