查询词典 intracortical

The result presented a direct morphological evidence for weakness of GABAergic intracortical inhibition ,which is considered to be a possible candidate for neural basis of age-related visual function decline, and further suggested that GABAergic neuron loss and decreased GABA synthesis might be responsible for above degradation.

本文结果为皮层内GABA能抑制系统减弱可能是介导老年性视觉功能衰退的机制提供了直接的形态学证据，且进一步提示：GABA能神经元的丢失和递质合成的减少可能是介导以上所述的功能衰退的重要因素。

Rats were trained for three or five days in a skilled reaching task with one forelimb, after which slices of motor cortex were examined to determine the effect of training on the strength of horizontal intracortical connections in layer II/III.

我们对鼠进行为期3至5天的训练其一只前肢技能，而后检测运动皮质切片获悉训练对II/III水平内皮质连结强度的影响。

The result indicates that the intracortical synaptic input was unchanged, but the thalamocortical synaptic input was depressed by sensory stimulation and this depression recovered with a time course that matched that of the recovery of sensory responsiveness.

结果表明，电刺激诱导出的皮层—皮层突触反应不受持续的触须刺激的影响，而电刺激诱导出的丘脑—皮层突触反应则由于持续的触须刺激而减小，而且突触反应的恢复时程与皮层细胞适应恢复的时程类似。

By comparing the tuning width of the input and output tuning curves, it is shown that the orientation selectivity is sharpened after being processed by the intracortical connection.

将同一神经元的输入和输出曲线进行比较可以看出，经过视皮层内神经回路加工以后，方位调谐曲线的宽度变窄，调谐特性被明显地锐化。

Moreover, the S1 area was shown to be more easily activated and more intensively innervated by the thalamocortical afferent projections than by the intracortical connections.

其次，刺激IV层在每一刺激强度下诱发的场电位幅度远远大于刺激II-III的场电位幅度，即S1区更容易被丘脑皮层连接回路的投射纤维所激活。

Classic histopathology is eosinophilic homogenization of thickened walls in leptomeningeal and intracortical small blood vessels.

其典型组织病理学表现为软脑膜和皮质内小血管壁增厚均质嗜红染。

The rat hindlimb representation of S1 area is likely to have at least 2 patterns of neural circuits on brain slices: one is the intracortical circuit formed by interlaminar connections from layers II-III, and the other is the thalamocortical circuit mediated by afferent connections from layer IV.

相反，在II-III层，同样的强直刺激并未能明显诱导LTP的发生。结论大鼠S1区的后肢代表区似乎存在两种不同类型的神经回路，一种是由层间联系介导的皮层内回路，另一种则是由丘脑皮层传入介导的丘脑皮层连接回路。

To estimate the contribution of thalamocortical and intracortical synapses to rapid adaptation, we applied electrical stimulation in VPM and barrel cortex and compared the electrical evoked responses of cortical neurons before and after adapting stimulation.

为了了解丘脑—皮层突触和皮层—皮层突触对皮层细胞快速适应的贡献，实验中分别在VPM和体感皮层施加电刺激，研究持续的感官刺激对电刺激诱导出的皮层细胞反应的影响。

Results The local intracortical connection, which is involved in mediation of downward information flow across layers II-VI, was identified by electrical stimulation at layers II-III.

结果 刺激S1后肢代表区脑片的II-III层，可鉴定出局部皮层内的连接回路，而刺激IV层则鉴定出丘脑皮层间的连接回路。

GroupⅡ Six months after internal fixation, the cortex under the plate was so markedly disorganized that the whole layer of it was cancellized. At this time, the intracortical bone porosity was going up to 26 per cent.

本研究还表明，坚硬接骨板取出后骨量恢复和骨结构恢复并不是同步完成的，骨结构恢复往往迟于骨量恢复，而骨结构恢复延迟又可导致骨强度恢复延迟。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
