Siddharthan Chandran: Can the damaged brain repair itself

After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn t happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig s disease or ALS). Siddharthan Chandran walks through some new techniques using special stem cells that could allow the damaged brain to rebuild faster.
