Memory
consolidation is a process which stabilizes a short-term memory into a
long-term memory. Consolidation occurs after the initial learning lasting for
a period of time. In this study, we employed resting-state experiment design
to reveal the functional connectivity among hippocampus, PCC, and MTG during
consolidation of memorizing easy and difficult words that would result in
good and poor memory respectively. As seeds set at three ROIs, we detected
increase connection with cuneus in the hard condition, implying the
engagement of visual analysis; increment in connection with cerebellum and
frontal cortex in the easy condition, reflecting the on-going consolidated
activity.
