Research on prairie voles has shown that social interaction boosts brain connections linked to bonding. These voles form strong pair bonds, making them a useful subject for studying attachment.
A study found that even brief contact with a male alters brain structure in areas linked to reward, increasing neuron connections in female prairie voles.
As noted, social interaction has a significant impact on the brain structure of female prairie voles, particularly in areas related to reward and bonding.
