A research team led by Professor Grigori Enikolopov of Cold Spring Harbor Laboratory (CSHL) conducted experiments on mice to assess the impact of social stress upon the mice, both at the time they are experienced and during adulthood.

According to sources, the experiment showed that in young mice chronic social defeat induced high levels of anxiety helplessness, diminished social interaction and diminished the ability to communicate with other young animals.

Other group of young mice was also exposed to social stress but was later placed in an unstressful environment. After weeks, the mice now old enough to be considered adults, were tested in the same manner as the other group.

It was found that most of the behaviors impacted by social defeat returned to normal, as did neurogenesis, which returned to a level seen in healthy controls.
