Knowing what from where: Hippocampal connectivity with temporoparietal cortex at rest is linked to individual differences in semantic and topographic memory.

摘要: The hippocampus contributes to episodic, spatial and semantic aspects of memory, yet individual differences within between these functions are not well-understood. In 136 healthy individuals, we investigated whether reflect variation in the strength connections functionally-specialised segments diverse cortical regions that participate different memory. Better topographical memory was associated with stronger connectivity lingual gyrus left anterior, rather than posterior, hippocampus. increased intracalcarine/cuneus left, right, posterior Notably, observed a double dissociation memory: better temporoparietal cortex anterior hippocampus, while topographic linked right Together data support division-of-labour account hippocampal functioning: at population level, across functional specialisation for facets patterns individuals is capacity retrieve types information. particular, within-hemisphere supports conceptual processing expense ability.
