The representation of social interaction in episodic memory: a functional MRI study.

摘要: The representation of social interaction in episodic memory is a critical factor for the successful navigation relationships. In general, it important to separate during from self-generation action events. Different cortical representations have been associated with vs. self-generated memory. Here we clarified effect context (social solitary) on by comparing generation (self other) Each participant learned words while engaged sentence and reading task, subsequently each was scanned functional magnetic resonance imaging (fMRI) they performed recognition task using that had learned. experiment comprised four conditions looked at two situations involved non-social (solitary) task. learning session before entering MRI, participants collaborated either generating (social-contextual condition: SS) or other-generation SO) sequence sentences alternately construct meaningful story narrative. context, generated (non-social-contextual NS) read NO) individually. stimuli consisted novel words. Activation retrieval identified right medial prefrontal cortex (mPFC), activation left mPFC middle cingulate cortex. These results indicate dissociable regions within cortices contribute processes interaction, including
