The role of the default mode network in representing and remembering mental states - Project Summary Understanding others' thoughts and feelings is central to human experience, yet little is known about how this process of mentalizing shapes event memory. Both mentalizing and episodic memory engage the default mode network (DMN), and it has been proposed that there are parallel subnetworks supporting episodic retrieval and mentalizing processes. However, it is unknown how engagement of these subnetworks during encoding of social events influences memory content and recall structure. We hypothesize that the DMN supports both mentalizing and episodic memory but that its subnetworks make distinct contributions to encoding information about mental states. In Aim 1, we will conduct an fMRI study to examine the influence of mentalizing on the neural bases of episodic memory encoding. In Aim 2, we will leverage an existing fMRI dataset to determine whether neural alignment of the DMN during memory encoding is related to similarities in recall of social information. Across both studies, we aim to elucidate DMN dynamics at a subsystem level by linking its activity and functional connectivity during event encoding to subsequent memory. This approach will provide insight into the DMN's contributions to complex cognitive processes using a combination of well- controlled experimental designs and naturalistic events. Modeling network dynamics of social memory will elucidate neural substrates underlying impairments in both episodic memory and social interaction, thereby informing potential interventions for clinical populations with related disorders.
