On the other hand, neuronal regenerative activity was detectable in analyzed CA1, CA2, and CA3 subfields of the rat hippocampus analyzed on the basis of 5-bromo-2-deoxy-uridine (BrdU) labeling assay; however, this activity in treated group was not significantly different from that of control ...

CA4is often called the hilus or hilar region if considered as a part of the dentate gyrus. Unlike the pyramidal neurons in CA1 and CA3, the neurons here include mossy cells that primarily receive inputs from the granule cells in the dentate gyrus in the form of mossy fibers.[2][3] The...
The calculation of hippocampal subregions confirmed the estimates that the volume of CA1 (547.1 mm3) is about half of the entire hippocampal formation (Sub 289 mm3, CA2 41.6 mm3, CA3 55.6 mm3, CA4 110 mm3 and DG 110 mm3). Fig. 1: Single image analysis. a, Cell body...
Synaptic plasticity in the lamellar CA3 to CA1 circuitry has been extensively studied while interlamellar CA1 to CA1 connections have not yet received much attention. One of our earlier studies demonstrated that axons of CA1 pyramidal neurons project to neighboring CA1 neurons, implicating ...
Hippocampusis divided into three areas, CA1, CA2 and CA3, which form a circuit called thetrilaminar loop of hippocampus(processing center of LTM). The loop is briefly described here. Signals enter via axons of theentorhinal cortex, and terminate in thedentate gyrus. This forms the first loop...
the hippocampus is often considered an inward protrusion of the temporal horn of the lateral ventricle.4. It is composed of four distinct regions: CA1, CA2, CA3, and CA4. Information enters the hippocampus through the dentate gyrus, flows into CA3, and then to CA1 before reachin...
