Science Friday > Archives > 1999 > October > October 22, 1999: Hour One: Brain Update Last week, scientists at Princeton University made an announcement that goes counter to long-held wisdom about the brain. They discovered that new neurons are continually being added to the brains of monkeys, even to parts of the brain responsible for very high-level functioning. 
Once, it was believed that no new brain cells were created after hood. Later, it was found that some parts of the brain such as the hippocampus, could regrow cells. The work, reported in the October 15th issue of Science, means that neurogenisis may be much more common than previously thought. We'll talk about what the research might mean for learning, memory, and the treatment of neurological diseases. Other researchers have been trying to regrow brain cells in another way - by using generic "neural stem cells" that the body can develop into many different types of neural tissue We'll find out about efforts to clone theses neural stem cells, and how cells like these might be used in disease treatment. We'll also find out about a discovery announced this week by researchers at Amgen (Full disclosure: Amgen is one of Science Friday's funders on NPR.) The researchers, writing in this week's edition of the journal Science, report that they have located an enzyme that they believe is involved in the formation of "plaque" in the brains of people with Alzheimer's disease. While the existence of the enzyme has been assumed for a long time, it had never been actually isolated before. Might the discovery be of use someday for treating Alzheimer's? We'll find out.
