Early Memory

AbstractAutobiographical memory (AM) unfolds over time, but little is known about the dynamics of its retrieval. Space-based models of memory implicate the hippocampus, retrosplenial cortex, and precuneus in early memory computations. Here we used inhibitory continuous theta burst stimulation (cTBS) to determine the causal role of the precuneus in the temporal dynamics of AM retrieval. Compared to vertex, precuneus stimulation altered evoked neural activity during early memory construction, as early as 400 ms after cue presentation, as well as during later memory elaboration. We further identified a parietal late positive component during memory elaboration, the amplitude of which was associated with spatial perspective during recollection. Precuneus stimulation disrupted this association, suggesting that this region plays a crucial role in the neural representation of spatial perspective during AM. These findings help clarify the neural correlates of early memory retrieval and demonstrate a causal role for the precuneus in the temporal dynamics of AM retrieval.

Data Call

Autobiographical memory (AM) defines the memory systems that encode, consolidate, and retrieve personal events and facts, AM is strongly related to self-perception and self representation. We review here the neural correlates of AM retrieval. AM retrieval encompasses a large neural network including the prefrontal, temporal, and parietal cortex, and limbic structures. All these regions subserve the cognitive processes (episodic remembering, cognitive control, self-processing, and scene construction) at play during memory retrieval. We emphasize the specific role of medial prefrontal cortex and precuneus in self-processing during autobiographical memory retrieval. Overall, these data call for further studies in psychiatric patients, to investigate the neural underpinnings of autobiographical memory and self-representation in mental disorders.

Abstract. We examined whether interindividual differences in cognitive functioning among older adults are related to episodic memory engagement during autobiographical memory retrieval. Older adults ( n = 49, 24 males; mean age = 69.93; mean education = 15.45) with different levels of cognitive functioning, estimated using the Montreal Cognitive Assessment (MoCA), retrieved multiple memories (generation task) and the details of a single memory (elaboration task) to cues representing thematic or event-specific autobiographical knowledge. We found that the MoCA score positively predicted the proportion of specific memories for generation and episodic details for elaboration, but only to cues that represented event-specific information. The results demonstrate that individuals with healthy, but not unhealthy, cognitive status can leverage contextual support from retrieval cues to improve autobiographical specificity.
