Rats are social species, but few labs socially house rats in large groups. In the NAC lab rats are socially housed so that the cognitive and neural effects of sociality can be quantified. We have also assessed the emergence of dominance hierarchies throughout development and how social housing vs. non-social housing effects motivation for future social interactions; see Templer, Wise, Dayaw, Dayaw (2018)
