文摘

Hippocampus plays a critical role in relational memory. Hippocampal volume correlated with magnitude of reactivation in sensory cortex. MR diffusion measures within hippocampus correlated with magnitude of reactivation. Older adults show relational reactivation like that found in younger adults. Magnitude of reactivation is related to subsequent memory.
