New Cells From Old Brains

Scientists have found that the adult human brain can create new cells, opening the door to new therapies to possibly halt and even reverse paralysis and damage from degenerative nerve disease.

This week, scientists from New Zealand and Sweden report they not only located an elusive passageway—called the rostral migratory stream (or RMS)—in the human brain, but also found cells in the process of differentiating into neurons along this structure.
