Results Leptin depolarized the most neurons of the three model animal groups and hyperpolarized the minor neurons, but there had no significant difference among the three groups.

结果 瘦素使三组动物大部分神经元去极化，各组间比较差异无显著性。

These results suggest that in the central nervous system of small mammals, AP waveforms mature rapidly in many types of neurons, thus, coordinated activities in neuronal circuits may occur. In early postnatal development, GABA receptor mainly mediates an excitation effect, depolarizes P6 MGBv neurons and dramatically increases the frequency of AP firing. Inhibition of GABA receptor matures slowly along with increment of postnatal days.

结论大鼠MGBv神经元的AP波形成熟较快，可在中枢神经系统的神经元环路中产生协调性的活动；在MGBv神经元发育早期，GABA主要作为兴奋性神经递质而发挥作用，它可使P6的MGBv神经元产生去极化，AP发放频率显著增加，随着出生后日龄的增加，GABA受体的抑制作用才逐渐发育成熟。

Using whole-cell patch clamp recording, we observed multiple distinct ATPinduced currents in isolated DRG neurons of adult rats, each with unique desensitizing kinetics.β,γ-meATP, agonist of P2X1 receptor also induced fast inactivating and slowly desensitization current in small DRG neurons. PDBu, a selective agonist for PKC, decreased the P2X receptor-mediated inward currents in a dose-dependent manner, while SNP, nitric oxide donor, potentiated the ATP-evoked current through NO-cGMP pathway.

全细胞膜片钳记录观察到，在成年鼠离体DRG伤害性感受相关的小直径神经元上，ATP可诱导出多种具不同反应型式及脱敏动力学的由P2X受体介导的内向流；P2X1受体激动剂β，γ-meATP亦可诱导出快脱敏及慢脱敏两种型式的内向流；PKC激动剂可剂量依赖地削弱P2X受体介导的内向流，而NO供体硝普钠可通过NO-cGMP通途显著易化ATP介导的内向流。

There is evidence for process outgrowth from the engrafted neurons, and for synaptic connections with host motor neurons.

这是移植神经元生长的一个证据，同宿主的运动神经元细胞通过突触连接。

Extracellularly recording the responses of dLGN neurons to sinusoidal gratings with different orientations showed that optimum orientations of dLGN neurons in trained cats, compared with that in untrained cats, did not shift in favour of the trained orientation. For cells with receptive fields located within 15°visual acuity away from the foveae, there are no difference in orientation bias and firing rate at trained orientation between the trained cats and untrained cats.

细胞外记录外膝体背核神经元对不同方位正弦光栅刺激的反应显示，垂直或水平方位正弦光栅信号训练的猫，与正常猫相比，其外膝体细胞的最优方位并未向着训练方位发生明显改变，对于感受野位于中央区15 度视角以内的细胞来说，其方位选择性强度以及在训练方位的发放强度与正常猫无明显差异。

Results After spinal cord hemisected, the number of CN and RN neurons was decreased obviously, the area of CN was diminished, and the NOS positive neurons of CN were increased at lesioned side in the control group.

结果 脊髓半横断后，对照组损伤侧背核神经元和红核神经元数目明显降低，背核面积减少，背核NOS阳性神经元增多。

Although the number of NPY-Ir neurons innervating the cerebral arteries in SCG was increased by 17% after 4-week simulated weightlessness, the NPY-Ir labeling intensities in the neurons was not markedly changed.

模拟失重4周后，支配脑动脉的颈上交感神经节NPY-Ir神经元数量增加约17％，但NPY-Ir标记强度没有明显差异。

In the first study to show how these "baby" neurons are integrated into the brain's existing networks, the Johns Hopkins researchers show that a brain chemical called GABA readies baby neurons to make connections to old ones.

然而，美科学研究显示包括人在内的所有成年动物的大脑都会制造新的神经细胞，并且可以成为成人大脑系统的一个工作部分。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
