HIPPOCAMPUS (Brain)COMPUTER simulationCOINCIDENCE circuitsThe aim of this paper is to present a computational model of the CA1 region of the hippocampus, whose properties include (a) attenuation of receptors for external stimuli, (b) delay and decay of postsynaptic potentials, (c) modification of ...
近几十年 来,科学家们致力于研究大脑是如何形成记忆的,而其中海马是最受关注的脑区之一。 在体多神经记录技术的发展,结合巧妙设计的行为学实验,加上强大的神经计算方法, 使得这个领域的研究取得了显著的成果,初步发现了海马CAl区对外部情景事件编码 并形成记忆的基本机制。 海马神经元的种类并不是单一的,除了主要...
Oscillations in the brain reflect the temporal organization of local circuit activity and play key roles in a range of cognitive processes1,2. In the CA1 region of the hippocampus, three prominent bands of oscillations dominate the local field potential (LFP); theta (4–12 Hz), gamma (30...

Conclusion: The CA1, CA3 and DG regions of the hippocampus of Wistar rat could be divided under stereomicroscope, andthe divided each region was sensible for detection of protein using Western blot.= KEY WORDS> rat; hippocampus; CA1; CA3; dentate gyrus Lorente de No 将海马分为 Cornu Ammon...
Abstract :Objective To improve the administration method of lentiviral vector in rat CA1 region of hippocampus by electrode pipe installation and detect its validity and security .Methods Fourty‐five male healthy SD rats were randomly divided into three groups :sham operation group (SH) , normal ...
The hippocampus is an essential brain area for learning and memory. However, the network mechanisms underlying memory storage, consolidation and retrieval remain incompletely understood. Place cell sequences during theta oscillations are thought to be re
Methods: We immunostained brain sections from young to old mice with some putative markers. Results: Here, we found that the extracellular deposits increased in CA1 and CA2 regions of hippocampus and layer II and III regions of entorhinal and piriform cortex of aged mice which are the earliest...
Paired-pulses of 20-100 ms interpulse interval (IPI) were delivered to the Schaffer collaterals/commissural fibers in order to excite the apical dendrites of the hippocampal CA1 region in freely behaving rats. Significant differences were observed for the paired-pulse responses during different behavi...
作者: The medial temporal lobe,including the hippocampus 摘要: The medial temporal lobe, including the hippocampus, has been implicated in social memory. However, it remains unknown which parts of these brain regions and their circuits hold social memory. Her ......
