The frequencies of neuron discharges were compared in animals in the state...
海马具有高度分化的片层结构,一方面,海马神经环路在片层中的分布有一定的空间规律,如锥体细胞胞体分布在锥体细胞层,而雪氏侧支突触分布于辐射层,且海马中存在一个三突触联系的回路,即穿通纤维-齿状回颗粒细胞层、苔状纤维-CA3区锥体细胞层、雪氏侧支-CA1区锥体细胞层等,因此,在海马中可以较准确地记录到特定神经...
Summary: CA3 region of hippocampus may be considered as an initial store-room for memories. During spatial memory tasks CA3 cells were found to fire in single well defined portions of a recording room (place-fields), whereas cells in both of its afferent regions, entorhinal cortex (EC) and ...
In growing towards their hippocampal targets, incoming afferent axons from the entorhinal cortex arrive at the subicular pole of the hippocampus and normally turn pialwards from the alvear path, crossing (perforating) the subiculum and field CA1, but never the more distally situated field CA3. ...
we have proved the hypothesis that the descending phase of the theta rhythm in the CA1 field is formed by the input from the CA3 field via the Shaffer collaterals, and the ascending phase of the theta rhythm is formed by the inhibitory postsynaptic potentials from CCK basket cells. The slow...
“place”) learning and memory, requiring the integrity of the hippocampus for optimal performance. The water maze, however, is oftenconsideredsynonymouswith “learning and memory.” In reality, learning and memory are complex and multidimensional (Willingham, 1997;Kessels et al., 2001) and care ...
We studied the processes of inhibition and facilitation in the dentate gyrus (DG) and the CA3 field by examining the effects of paired-pulse stimulation on the evoked population spike (PS) in dorsal (DH) and ventral (VH) hippocampal slices from the adult rat. The antidromic–orthodromic (A–...
At the level of the CA1 area of the hippocampus, the most interesting observation was the similar pattern of spectral power increase induced by learning of operant conditioning from session 1 to session 10 in both WT and PVKO strains for the 4–30 Hz frequency range (i.e., for θ and ...
Estradiol treatment increased norepinephrine levels in CA3 region of the hippocampus, mitigating stress-dependent changes. Both stress and estradiol decreased dentate gyrus levels of 5-hydroxyindole acetic acid. In summary, the current study provides novel information showing that estradiol alters behavioral...
