Functional Connectivity in Hippocampal Sub‐Regions as a Function of Age, Sex, and ApoE e4 Status

Olfactory disturbances, thought to be related to preclinical neuropathology and functional decline of the medial temporal lobe, are a reliable predictor of later Alzheimer’s Disease (AD) onset (Murphy, 2019). This study focused on the relationship between hippocampal functional connectivity, olfaction, and risk factors for AD by studying the sub‐regions of the hippocampus independently.
