Neural dedifferentiation in the aging brain

JD Koen, MD Rugg - Trends in cognitive sciences, 2019 - cell.com
Many cognitive abilities decline with age even in the absence of detectable pathology.
Recent evidence indicates that age-related neural dedifferentiation, operationalized in terms …

Space, time, and episodic memory: The hippocampus is all over the cognitive map

AD Ekstrom, C Ranganath - Hippocampus, 2018 - Wiley Online Library
In recent years, the field has reached an impasse between models suggesting that the
hippocampus is fundamentally involved in spatial processing and models suggesting that …

Significance of visual scene‐based learning in the hippocampal systems across mammalian species

SM Lee, J Shin, I Lee - Hippocampus, 2023 - Wiley Online Library

Going beyond LTM in the MTL: a synthesis of neuropsychological and neuroimaging findings on the role of the medial temporal lobe in memory and perception

KS Graham, MD Barense, ACH Lee - Neuropsychologia, 2010 - Elsevier
Studies in rats and non-human primates suggest that medial temporal lobe (MTL) structures
play a role in perceptual processing, with the hippocampus necessary for spatial …
