New neurons flatten social hierarchies (opens in new tab)

As complex individualized behaviors in mice arise even when genes and environment are held constant, emerging social group structures should also depend on individual behavior. Adult hippocampal neurogenesis drives individual behavior and is involved in certain social behaviors. Would thus the emergence of social structure depend on adult-born neurons? To answer this question, we co-housed cohorts of female mice with intact and genetically diminished general adult neurogenesis in a large-scal...
