Picking our brains: Can we regenerate the brain?

Posted: April 5, 2010 at 2:21 am

Story Summary: In the 1990s, decades of dogma were overturned by the discovery that mammals, including people, make new neurons throughout their lives. Lindvall is now looking for ways to make these specialised neurons from embryonic stem cells or stem cells made by reprogramming adult skin cells. Macklis has shown that in animals at least, these progenitors can be directed to form functional neurons. In mice, he has found chemical cues that tip progenitors into becoming motor neurons, the cells damaged by motor neuron disease. Im a great optimist with respect to regulating neurogenesis in normally non-neurogenic parts of the brain. But the nervous system was built with precision, and we will have to rebuild it with that precision.
