The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus. Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.

2011年10月10日 · In patients with a rare acute transient global amnesia, highly focal lesions confined to the CA1 field of the hippocampus can be detected on MRI. We studied the effect of these lesions on autobiographical memory using a detailed autobiographical interview including the remember/know procedure.

Within the hippocampal memory system, CA1 neurons are critically involved the formation, consolidation, and retrieval of hippocampal-dependant memories. Recent high-resolution volumetry did show an association between CA1 volume and episodic memory retrieval ( 38 ).

The CA1 hippocampal region is related to memory consolidation process and CA3 to retrieval of memories (Ward et al., 2009). The memories can be classified according to the function, content, duration, nature, and motivation.

2024年1月20日 · The CA1 region, often referred to as the gateway to the hippocampus, plays a critical role in the process of memory formation and retrieval. CA1 is located at the proximal end of the hippocampus, adjacent to the subiculum.

2023年3月23日 · We have benchmarked the method to the Cornus Ammonis-1 (CA1) region of a right human hippocampus by creating the 3D positioning of all pyramidal cells (PCs) and interneurons as well as the...

We used coronal sections of the human hippocampus at the level of the hippocampal body and examined the CA1 field at both light and EM levels. Following a deep to superficial axis, the following main CA1 layers were analyzed: the alveus, stratum oriens (SO), stratum pyramidale (SP), stratum radiatum (SR) and stratum lacunosum-moleculare (SLM ...

2024年4月23日 · To test whether biophysical properties of human Cornu Amonis subfield 1 (CA1) pyramidal neurons can explain observed rhythms, we map the morpho-electric properties of individual CA1 pyramidal neurons in human, non-pathological hippocampal slices from …

2011年10月18日 · In patients with a rare acute transient global amnesia, highly focal lesions confined to the CA1 field of the hippocampus can be detected on MRI. We studied the effect of these lesions on autobiographical memory using a detailed autobiographical interview including the remember/know procedure.

In the hippocampus, a vital region of the brain responsible for memory, four subfields—CA1, CA2, CA3, and CA4—play crucial roles in this process. Understanding how these subfields contribute to memory processing is essential for researchers and those interested in neuroscience.
