Spying On New Neurons In the Human Brain

摘要

The realization more than a decade ago that the mammalian brain produces new neurons well into adulthood was a revolution in neurobiology .It also raised a slew of questions about the function of these new cells. In recent years, for example, scientists have debated whether newborn neurons aid learning and memory and whether aberrations in adult neurogenesis contribute to disorders such as depression (Science, 17 February 2006, p. 938; 8 August 2003, p. 757).
