Here's a news article summarizing the article: Brain’s Social Bonding Mechanism Unveiled. The original research:

Jun Kunimatsu, Hidetoshi Amita, and Okihide Hikosaka, Neuronal response of the primate striatum tail to face of socially familiar persons, iScience, May 22, 2024DOI:https://doi.org/10.1016/j.isci.2024.110043

Highlights

• Neurons in the striatum tail strongly respond to socially familiar faces
  
• The face-responsive neurons in the striatum tail encode long-term object value
  
• Strength of social familiarity and object value coding are positively correlated
  
• Social familiarity and object value information may be mediated by a common ...
