Genetic Manipulation Boosts Growth of Brain Cells Linked to Learning

Scientists at UT Southwestern Medical Center have discovered a way to manipulate genes to increase the development of brain neurons during aging.  Also, the manipulation increases the effectiveness of antidepressant drugs.  This is significant because it suggests that, in the future, we will be able to prescribe more effective antidepressant drugs in smaller doses.  Antidepressant effectiveness is less-than-optimal at this point in time, and this could be a turning point.
