Slow brain repair seen in Huntington’s

From Orlando, Fla., at a meeting of the Society for Neuroscience

The human brain may struggle heroically, but in vain, to replace the nerve cells that die in Huntington’s disease, a New Zealand research team suggests.

Over the past few years, neuroscientists have been surprised to find that healthy, adult mammalian brains generate new nerve cells from so-called stem cells residing in select regions of the brain.
