Memory and the dynamic human social environment Micah Edelson University of Zurich Human memory is strongly influenced by the social environment, yet the underlying mechanisms of this process are unknown. Using behavioral, pharmacological and imaging techniques we explored how long-lasting mnemonic representations can be altered via social influence, whether it is possible to recover from such influence, and how these processes can be externally controlled. Our results suggest that the social milieu influences memory via hippocampal and amygdala circuits while the ability to overcome social influence is subserved by specific prefrontal activity. We find that the interplay between these systems may determine the balance between memory change and overt compliance and can be influenced by intranasal oxytocin administration.
