Hippocampus, model excitatory cells refer to mathematical models of neurons that are designed to represent excitatory neurons in hippocampus. Here, we focus on biophysically motivated models of excitatory cells in the hippocampus proper (specifically the CA1 and CA3 pyramidal cells) and the granule ce...

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...
Consistent with this bidirectional role, neuronal activity in vH during approach and avoidance is heterogeneous. In the EPM, different neurons in the CA1 and subiculum region of vH fire upon entry into either the open arms or the closed arms of the maze4,12, suggesting that different ...
Thomas J.Gould,Prescott T.Leach, inNeurobiology of Learning and Memory, 2014 2.5Differences along the dorsal/ventral axis of the hippocampus In the previous section, thehippocampuswas presented as a homogenous structure with discrete subregions such as thedentate gyrus, CA3, and CA1; however, it...
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...
Images were taken with a 40 × objective (Nikon) for PER and LEC and a 20 × objective for CA1 and CA3 in z-stacks of 0.7-μm-thick images containing 12–16 images (see example Fig. 3). The exposure time, light intensity, contrast and gain settings were kept constant ...
我们利用最先进的技术来训练循环脉冲网络,以证明CA3和CA1中神经元的主要抑制网络如何能够:1)产生内部theta序列或"时间细胞",以在存在间隔抑制的情况下结合外部诱发的脉冲;2)去除间隔抑制后以SPW-R形式可逆地压缩学到的表征;3)在SPW-R介导的压缩过程中生成并重建gamma集合,以及4)调节纹波簇中SPW-R之间的纹波间隔...
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...
We assessed the overall hippocampal volume, and considered eight subregions across allocortical regions of the hippocampal formation29: the hippocampal tail (comprised of portions of CA and DG), CA1, CA3 (CA2 and CA3 are combined in the Freesurfer atlas), CA4, molecular layer (ML) of the sub...
