Parkinson's disease seems to be caused by degeneration of the cells in the brain which supply an essential chemical, dopamine. What if those cells could be replaced? Recent research on rats suggests that slivers of tissue taken from embryos can be successfully transplanted into adult brains. The transplants grow, and can form working connections.
Professor Colin Blakemore discusses how to remake the brain, and explores the implications for treatment of the host of human conditions caused by brain damage. Contributors include:
