Webb26 sep. 2013 · Magnetic resonance imaging (MRI) applied to the hippocampus is challenging in studies of the neurophysiology of memory and the physiopathology of numerous diseases such as epilepsy, Alzheimer’s disease, ischemia, and depression. The hippocampus is a well-delineated cerebral structure with a multi-layered organization. WebbObjectives: To characterize the structural plasticity of the contralesional hippocampus and its subfields in patients with unilateral glioma. Methods: 3D T1-weighted MRI images were collected from 55 patients with tumors infiltrating the left (HipL, n = 27) or right (HipR, n = 28) hippocampus, along with 30 age- and sex-matched healthy controls ...

Webb14 apr. 2024 · The LESA framework enables researchers to accurately identify shape changes on the subcortical surfaces. They discovered that atrophy of the hippocampus associated with Alzheimer’s disease primarily occurs in the back of the organ, which is where crucial parts, known as subfields CA1, CA1, CA2 and CA4, are located.
Webb27 juli 2024 · The fornix originates from the hippocampus in the mesial temporal lob e and stretches longitudinally to the diencephalon and basal forebrain, forming an arch over the thalamus. Being a part of the limbic system, the fornix is associated with the processes of cognition, memory consolidation, emotions and sexual responses. WebbThe data indicate that transient global amnesia may not be a benign entity and delayed neuronal loss within CA1 area of Lorente de No may represent its important sequel.

WebbThe hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located in the allocortex, with neural projections into the neocortex in humans, [1] [2] [3] as well as primates. [4] WebbAbstract. Background: In Alzheimer’s disease, neurodegenerative atrophy progresses from the entorhinal cortex (ERC) to the hippocampus (HP), limbic system and neocortex. The significance of very mild atrophy of the ERC and HP on MRI scans among elderly subjects is unknown. Methods: A validated visual rating system on coronal MRI scans was used …
