查询词典 thalamocortical

The thalamocortical afferent projections were likely to make more synaptic contacts with S1 neurons than the intracortical connections did.

与之相比，皮层内回路的激活引起的电反应活动范围则较小。

Under these two kinds of stimuli, thalamocortical pathway shows prominent properties of short-term synaptic depression, which is alike those of intracortical synapses.

在这两种刺激模式下，正常成年大鼠的丘脑皮层主要视觉通路均表现出明显的短时程抑制特性，并且与皮层内突触的特性相似。

Based on above results, we conclude that the synaptic depression of thalamic input to the cortex contributes to rapid adaptation in cortical neuron, and both the thalamocortical and intracortical synaptic transmission could then enhance the degree of adaptation.

基于以上结果，我们认为，持续刺激引起的丘脑—皮层突触的抑制对皮层神经元的快速适应有贡献，而丘脑—皮层突触以及皮层—皮层突触的放大机制都可以将这一特性进一步增强。

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。

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。

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。

Our work is concentrated on the possible mechanism of the formation and development of short-term plasticity of thalamocortical visual pathway in rats.

本工作对大鼠视通路短时程突触可塑性的形成机制和发育机制进行了研究。

Short-term plasticity has been found in thalamocortical pathways.

而且短效的神经可塑性也可以在视丘皮质路径中被观察到。

To understand the basic properties, underlying mechanisms and functions of the short-term synaptic plasticity of thalamocortical visual pathway, we combined in vivo field potential recording, focal drug application technique and neuron models, to explore the short-tem synaptic plasticity of rat major thalamocortical visual pathway (from lateral geniculate nucleus to primary visual cortex) and extrageniculate pathway (from lateral posterior nucleus to primary visual cortex), as well as the role of short-term depression in the neuronal correlated firing detection.

我们结合在位场电位记录、局部加药和神经模型等方法，对不同刺激模式下大鼠丘脑皮层主要视觉通路（外侧膝状体到初级视皮层）和非主要视觉通路（膝体外通路：丘脑侧后核到初级视皮层）的短时程突触可塑性，以及短时程抑制作用对神经元同步活动检测的作用做了研究，试图了解视觉丘脑皮层突触传递短时程可塑性的基本特性、神经机制和功能。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
