DOI: 10.1002/hbm.23891
Abstract: Automated segmentation of hippocampal (HC) subfields from magnetic resonance imaging (MRI) is gaining popularity, but automated procedures that afford high speed and reproducibility have yet to be extensively validated against the standard, manual morphometry. We… read more here.

DOI: 10.1002/hbm.24443
Abstract: Reexperiencing symptoms in adolescent Post‐Traumatic Stress Disorder (PTSD) are characterized by the apparition of vivid intrusive images of the traumatic event. The emergence of these intrusions is thought to be related to a deficiency in… read more here.

Cytoarchitectonically‐driven MRI atlas of nonhuman primate hippocampus: Preservation of subfield volumes in aging
Sign Up to like & getrecommendations! Published in 2019 at "Hippocampus"
DOI: 10.1002/hipo.22809
Abstract: Identification of primate hippocampal subfields in vivo using structural MRI imaging relies on variable anatomical guidelines, signal intensity differences, and heuristics to differentiate between regions (Yushkevich et al., 2015a). Thus, a clear anatomically‐driven basis for… read more here.

DOI: 10.1007/s00592-020-01670-x
Abstract: Neurodegeneration and microvascular lesions are related to cognitive impairment in type 2 diabetes mellitus (T2DM). We aimed to use the volume of hippocampal subfields and the burden of white matter hyperintensities (WMH) as neurodegeneration and… read more here.

DOI: 10.1016/j.brainres.2018.02.007
Abstract: OBJECTIVE Attention-deficit hyperactivity disorder (ADHD) is accompanied by reduction of total hippocampal volume. However, disorder-related fine-grained structural alterations of hippocampal subfields remain unclear. METHOD Here we compared hippocampal subfield volumes in a large sample of… read more here.

DOI: 10.1016/j.mri.2019.03.014
Abstract: Magnetic resonance imaging (MRI) is an important tool for analysis of deep brain grey matter structures. However, analysis of these structures is limited due to low intensity contrast typically found in whole brain imaging protocols.… read more here.

DOI: 10.1038/mp.2016.262
Abstract: Volume reduction and shape abnormality of the hippocampus have been associated with mood disorders. However, the hippocampus is not a uniform structure and consists of several subfields, such as the cornu ammonis (CA) subfields CA1–4,… read more here.

DOI: 10.1038/s41598-021-90364-7
Abstract: The hippocampus is critical for learning and memory and may be separated into anatomically-defined hippocampal subfields (aHPSFs). Hippocampal functional networks, particularly during resting state, are generally analyzed using aHPSFs as seed regions, with the underlying… read more here.
