This fact led me to speculate that an axon could find its retinal cell neighbors in the tectum by homing in on chemical scents released by active tectal neurons, because its neighbors were most likely at the source of this trail .

这让我怀疑，轴突是否可以藉著活跃的顶盖神经元释出的化学物质，找到顶盖里的视网膜细胞邻居，因为它的邻居最有可能就在这条路的起点。

In vivo whole-cell recording from the tectum of Xenopus tadpoles showed that repetitive dimming-light stimulation applied to the contralateral eye resulted in persistent enhancement of glutamatergic inputs, but not GABAergic or glycinergic inputs, on tectal neurons.

从爪蟾蝌蚪顶盖记录的活体整细胞显示，在对侧眼的重复低亮度刺激导致谷氨酸输入的持续增强，但顶盖神经元的GABA能或甘氨酸能的输入则不然。

In vivo whole-cell recording from the tectum of Xenopus tadpoles showed that repetitive dimming-light stimulation applied to the contralateral eye resulted in persistent enhancement of glutamatergic inputs, but not GABAergic or glycinergic inputs, on tectal neurons. This enhancement can be attributed to potentiation of retinotectal synapses.

在生体培养爪蟾蝌蚪四叠体中，以微暗的环境下激发对侧的的眼睛，可造成强烈激化麸胺酸型的突触传导，但却不激发胺基苯甲酸型与甘胺酸型的突触传导。

Retinotopic inputs to the optic tectum have been thoroughly mapped, but now Sato et al. map tectal efferents that project to the premotor reticulospinal system of the hindbrain.

视网膜区域定位输入信号到视顶盖已经得到了充分的定位，现在Sato等人绘制了覆盖层传出神经，它们投射到后脑的网状脊髓系统。

Results Higher density of retinal cells and tectal extract facilitate cultured RGCs to survive.

结果 较高的细胞接种密度或加入顶盖提取液(tectal extract，Te)均有利于混合培养的RGCs生长存活。

It required spiking of postsynaptic tectal cells as well as activation of NMDA receptors, and effectively occluded long-term potentiation of retinotectal synapses induced by direct electrical stimulation of retinal ganglion cells.

这需要突触后顶盖细胞的脉冲和NMDA受体活化，并有效闭塞连接视网膜和中脑顶盖神经纤维的突触长期的增强，这是由视网膜活动中心细胞的直接电激诱发的。

It appears that glutamatergic and cholinergic inputs from the retina, and cholinergic and gabaergic inputs from NI may converge on tectal neurons in anurans.

因比，从视网膜来的谷氨酸能、胆碱能输入和从峡核来的胆碱能、GABA能输入共存于顶盖神经元。

The depth of tectal layerⅠand the morphological characteristics of tectal cells in layerⅠwas investigated using Nissle staining, Golgi staining, and postmortem labeled with DiImethod. Most ofⅠcells appeared shuttle, others showed round, oval, pyramidal, triangular,and polygonal etc. The lateral region of layerⅠwas thicker than the ventral and the dorsalregions.

本研究使用Golgi-Cox法，灌流固定后尼氏体染色、羰花青荧光染料DiI(1，1′-dioctadecyl-3，3，3′，3′-tetramethylindocarbo-cyanine perchlorate)逆向神经标记技术，对雏鸡视顶盖Ⅰ层的厚度和该层的细胞形态、大小进行了观察研究和数理统计，并对不同日龄鸡胚的Ⅰ层厚度进行了数理统计及分析研究。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
