These results indicate that spike trains with various temporal structures will be synaptically transmitted between primary afferent fiber and spinal dorsal horn neuron.

这些结果表明具有各种时间结构的动作电位序列会在初级传入纤维与脊髓背角神经元之间进行突触传递。

Objective: To observe and study the expression of microtube-associated protein tau in neuron-oriented differentiation for neural stem cells.

Synaptic inputs activated repetitively within 20 ms before spiking of the tectal neuron become potentiated, whereas subthreshold inputs activated within 20 ms after spiking become depressed.

在四叠体突触尖波20ms前连续被激发的突触输入将造成突触电位化，然而在尖波产生的20ms后的小于临界输入将造成突触抑制。

Synaptic inputs activated repetitively within 20 ms before spiking of the tectal neuron become potentiated, whereas subthreshold inputs activated within 20 ms after spiking become depressed.

在四叠体突触尖波20ms前连续被激发的突触输入将造成突触电位化，然而在尖波产生的20ms后的小於临界输入将造成突触抑制。

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。

These results indicate that the genome of a post-mitotic, terminally differentiated neuron can re-enter the cell cycle and be reprogrammed to a state of totipotency after nuclear transfer.

这是非同小可的，因为供体神经元只表达一个这样的蛋白，而不是完整的一套蛋白，说明大脑中所表达的嗅觉受体的多样性不是嗅觉神经元DNA中永久排列的结果。

Results OECs showed bipolar or tripolar after 6-9 days of culture. Primary spinal cord neurons were round and bigger, and neuron axons grew significantly and showed bipolar after 5-7 days of culture.

结果 OECs 培养6～ 9 d 后，细胞多呈双极形或梭形；脊髓神经元胞体较大，多呈圆形，培养5～ 7 d 后，突起明显生长，多为双突起。

In order to further investigate the relationship of SP and ESCs, we design two level experiments —in vitro and in vivo. In vivo, firstly, We establish the nomal rat full-thickness wounds model, and employ integrin β1 keratin 19(K19)、 keratin 15(K15)、 Brdu as ESCs markers to conform the existence of ESCs in the granulation tissue of Group Capsaicin (rats were subcutaneously injected capsaicin pre-injury to damage sensory neuron and block the secretion of neuropeptides), Group Control, and Group SP (rats were injected SP in the wound postinjury). Secondly, as diabetic skin lacking of SP due to extensive pathological changes of sensory ending, we make a hypothesis:one of the main reason of unhealing wounds on diabetic patients could be insufficient SP which lead to fewer ESCs recruitment around wounds.

在此基础上，为进一步验证P物质促进表皮干细胞向肉芽组织中募集这一重要发现，本研究首先利用β1整合素、K19、K15等干细胞标记物以及干细胞慢周期性的特点，分别在体观察了正常皮肤伤口愈合过程中SP组、辣椒素组采用特异性感觉神经毒性药物辣椒素(capsaicin皮下预注射化学性除去感觉神经从而阻止神经肽分泌、对照组肉芽组织中表皮干细胞分布特点；其次，糖尿病患者皮肤存在周围末梢神经的损伤和神经肽含量的下降，这是否会导致糖尿病皮肤伤口创缘表皮干细胞募集不足，继发伤口难愈？
