Article Abstract:

Jennifer Brown discovered that mice without the gene fosB did not not nurture their young. Researchers have not yet determined if lack of the fosB gene directly controls the absense of nurturing or if the abnormal behavior is caused by a physiologic or anatomical defect caused by the deletion of fosB.
