abstract = {INTRODUCTIONHippocampal local and network dysfunction is
the hallmark of Alzheimer's disease (AD).METHODSWe
characterized the spatial patterns of hippocampus
differentiation based on brain co-metabolism in healthy
elderly participants and demonstrated their relevance to
study local metabolic changes and associated dysfunction in
pathological aging.RESULTSThe hippocampus can be
differentiated into anterior/posterior and dorsal cornu
ammonis (CA)/ventral (subiculum) subregions. While
anterior/posterior CA show co-metabolism with different
regions of the subcortical limbic networks, the
anterior/posterior subiculum are parts of cortical networks
supporting object-centered memory and higher cognitive
demands, respectively. Both networks show relationships with
the spatial patterns of gene expression pertaining to cell
energy metabolism and AD's process. Finally, while local
metabolism is generally lower in posterior regions, the
anterior–posterior imbalance is maximal in late mild
cognitive impairment with the anterior subiculum being
relatively preserved.DISCUSSIONFuture studies should
consider bidimensional hippocampal differentiation and in
particular the posterior subicular region to better
understand pathological aging.},
