1. GABAA受体活动介导的海马CA3-CA1区的同步性自发活动 目前关于海马的节律性活动的研究,主要集中在两个方面,一是海马细胞节律性活动产生的机制,另一方面是节律性活动的传播及如何影响群体细胞的同步化.我们发现离体完整海马可以自发产生低频节律性振荡(0.8-2Hz),而且同时记录的局部场电位和全细胞记录显示,这种自发...
MEMORYHIPPOCAMPUS (Brain)A synaptic network model is proposed to characterize both short-term and long-term memory. The model describes the calcium concentration-dependent bistability of CaMKII phosphorylation levels and the transition of CaMKII between DOWN and UP states under different stimulation ...

The CA1-projecting axons of CA3 pyramidal cells, called Schaffer collaterals, constitute one of the major information flow routes in the hippocampal formation. Recent anatomical studies have revealed the non-random structural connectivity between CA3 and CA1, but little is known regarding the ...
Recent studies have shown that place cells in the hippocampal CA1 region fire in a sequence sensitive manner. In this study we tested if hippocampal CA3 and CA1 regions can give rise to the sequence sensitivity. We used a two-layer CA3–CA1 hippocampal model that consisted of Hodgkin–Huxley...

Here we characterize step-like all-or-none transitions from baseline synaptic transmission to potentiated states following protocols for inducing potentiation at putative single CA3-CA1 synaptic connections. Individual synapses appear to have all-or-none potentiation indicative of highly cooperative processes...
