New research shows that these effects may persist in their children and even their grandchildren. Larry James and Lorena Schmidt, biochemists at the Tufts School of Medicine, caused chronic social stress in adolescent mice by regularly relocating them to new cages over the course of seven weeks. The researchers then tested these stressed mice in adulthood using a series of standard laboratory measures for rodent anxiety, such as how long the mice spent in open areas of a maze and how frequently they approached mice they had never met before. Female mice showed more anxious behaviors compared with control animals, whereas the males did not. Both sexes' offspring displayed more anxious behaviors, however, and the males who had been stressed as adolescents even transmitted these behavior patterns to their female grandchildren and great-grandchildren.
