Researchers have discovered a cell-producing region in the human brain that resembles one found in rodent brains -- but with a basic difference that has profound implications for research aimed at repairing damage by growing new cells.In rodents, a region called the subventricular zone (SVZ), roughly in the middle of the brain, constantly produces cells that migrate to the olfactory bulb, which governs smell. The rodent SVZ produces stem cells, which have the ability to be transformed into many different kinds of cells. Most end up as nerve cells.
