简介
Altered functional connectivity between dorsolateral prefrontal cortex (DLPFC), posterior hippocampus (HC) and other brain regions with advanced age may contribute to age-related differences in episodic memory. In the current fMRI study of spatial context memory, we used seed connectivity analysis to test for age-related differences in the correlations between activity in DLPFC and HC seeds, and the rest of the brain, in an adult life span sample. In young adults, we found that connectivity between right DLPFC and other prefrontal cortex regions, parietal cortex, precuneus, and ventral visual cortices during encoding was positively related to performance. Positive seed connectivity among these regions, and negative connectivity with posterior HC at retrieval was also positively correlated with retrieval accuracy in young adults. In older adults, activity in right DLPFC was positively correlated with activity in this same …
