Long-term behavioral and physiological consequences of developmental group size history in mice

Key Points

• Mice raised in larger groups show notable behavioral changes, including increased social interactions and altered stress responses.
• Significant differences in physiological effects, with a focus on hormonal changes related to group size history, demonstrate the impact of early life environment.
• Analysis across multiple developmental stages indicates that group size influences not only immediate behavior but also long-term physiological health.
• Understanding these effects supports greater insights into social behavior and development, suggesting potential analogs in other species.
