What they do know, says Dr. Jonathan Benjamin, an Israeli visiting scientist at the U.S. National Institute of Mental Health and co-author of the study, is that "when a molecule of dopamine arrives knocking on the door to a cell, the cell reacts a little bit more strongly in the people with the long version...
