Social isolation in early childhood can have life-long effects on social behaviors and development. Cerebellar crus I has additionally been linked to social behaviors through forebrain pathways. In this study, we hypothesized that social isolation of mice from postnatal day 21 (P21) until p35 would result in impaired social behaviors. Additionally, we hypothesized that gq DREADD injections into crus I, to increase levels of cerebellar stimulation, at the start of the isolation period would counteract the effects of isolation, leading to mice who displayed normal social behaviors. Social behavior at P35 was tested using the 3-Chamber Task, a well-established model, and SLEAP deep-learning software was used to obtain quantifiable data. We found no difference in social behaviors between socially raised and isolated mice. However, gq DREADD mice displayed greater levels of social interaction and exploration than either socially raised mice or isolated mice. This research carries implications for possible therapeutic interventions for groups prone to social isolation, such as those with developmental disabilities, minority groups, the elderly, and prison populations.
