The brain may be able to repair itself with help, Jocelyne Bloch

Through treating everything from strokes to car accident traumas, neurosurgeon Jocelyne Bloch knows the brain s inability to repair itself all too well. But now, she suggests, she and her colleagues may have found the key to neural repair: Doublecortinpositive cells. Similar to stem cells, they are extremely adaptable and, when extracted from a brain, cultured and then reinjected in a lesioned area of the same brain, they can help repair and rebuild it. With a little help, Bloch says, the brain may be
