A way of blocking the activity of specific pain-sensing neurons without affecting other sensory or motor neurons could be used to create a more targeted form of local anaesthesia, and that is the prospect held out by Binshtok et al. in this issue.

一种阻断特定痛觉神经元的这种活性而又不影响其他感觉或运动神经元的方法，也许可用来创建一种目标性更强的局部麻醉方法，而这正是Binshtok等人在本期Nature上提出的一个观点。

The results are indicated that only the strength of gap junction is large enough, can the abnormal oscillation propagate to synchronize the other neurons around and the process is chaotic and complex;the nonlinear and complexity of the oscillations with strong strength of gap junction are larger than that of oscillation with weak strength of gap junction.

结果表明：只有电突触耦合达到一定强度时，异常振荡才能传导并引起神经元的同步振荡；传导活动是混沌和复杂的；在突触耦合强度较强时的神经元活动的非线性和复杂性要强于其在突触强度较弱时的。

Single unit activities of the dorsolateral prefrontal cortex of the rhesus monkey were studied during the performance of color discrimination with delay.

在已学会颜色延缓分辨的3只猕猴上，用钨丝微电极记录前额叶背外侧部皮层神经元的放电活动，着重分析神经元放电活动与颜色延缓分辨活动的各个时期之间的相互关系。

In this paper, cholinergic neurons was mapped in the two kinds of birds (Emberiza rutila and Fringilla montifringilla) by using immunohistochemical method.The soma size and cell density of cholinergic neurons in the three song control nuclei, the higher vocal center, the robust nucleus of the archistriatum and area X, were measured and compared. Here we discussed the distribution of cholinergic neurons and their effect on the process of song producing and song learning.

本文以中国北方地区常见的两种鸣禽栗鹀和燕雀为材料，应用免疫组化方法，对两种鸣禽发声控制核团，即上纹状体腹侧尾核或高级发声中枢、古纹状体粗核、X区内胆碱能神经元的胞体大小和胞体密度进行了观察测量，旨在探讨胆碱能神经元在发声控制核团内的分布情况及其在鸣啭产生和学习过程中的作用。

AIM: Biological function and in vivo survival of differentiated dopaminergic neurons, and comparison to the transplantation of embryonic mesencephalic DNs for treating Parkinson's disease rats are seldom studied.

目的：目前对于体外诱导分化的多巴胺能神经元的生物学功能、体内存活状况，以及与胚胎中脑多巴胺能神经元移植治疗帕金森病大鼠的疗效比较方面尚缺乏深入的研究。

Methods Adopting electrophysiological methods, the extracellular discharge signals of neuronic action in NTS were recorded with glass microelectrode. The influence of the discharges of NTS neurons and gastric pressure responding to the acupuncture at "Zusanli" point were observed in normal status and the condition of Atropine or Metoclopramide intravenous injection.

采用神经电生理学方法，用微电极细胞外记录大鼠孤束核单个神经元的活动，在正常生理状态下及经血管注射抑制胃运动的药物阿托品或促进胃运动的药物胃复安后，观察针刺&足三里&对孤束核神经元放电及胃内压的影响。

We tested the possibility of selectively blocking the excitability of primary sensory nociceptor (pain-sensing) neurons by introducing the charged, membrane-impermeant lidocaine derivative QX-314 through the pore of the noxious-heat-sensitive TRPV1 channel.

With help of WLC model of inhibition nervous system and lobster neural structure of Mulloney's, neuron electric spike of lobster stomatogastric neural system was numerically analyzed and the changing activity of gastric network and pyloric network were obtained.

利用抑制神经系统的WinnerLess Competition模型，通过数值方法分析Mulloney 型龙虾胃肠神经系统神经元的电位发放，得到胃研磨囊和幽门神经系统中各个神经元的电位发放和系统的节律变化。

The results showed that the echolocation calls of the leaf-nosed bats were constant frequency-frequency modulation signals with 2-3 harmonics and the second one among these three harmonics was its dominant frequency. The constant frequency components of three harmonics (Mean±SD, n=18 ) were 33.3±0.2 kHz, 66.5±0.3 kHz, and 99.4±0.5 kHz, respectively. In examined FTCs of 72 IC neurons, their Q 10 -dB values ranged from 0.5 to 95.4 (9.2±14.6) and the neurons whose best frequency around the dominant frequency had sharp frequency tuning.

结果发现，大蹄蝠回声定位叫声为恒频-调频(constant frequency-frequency modulated，CF-FM)信号，一般含有2~3个谐波，第二谐波为其主频，CF成分频率(Mean±SD，n=18)依次为：(33.3±0.2)、(66.5±0.3)、(99.4±0.5)kHz；电生理实验共获得72个神经元的频率调谐曲线，Q10-dB值的范围是0.5~95.4(9.2±14.6， n=72)，最佳频率(best frequency，BF)在回声定位主频附近的神经元具有尖锐的频率调谐特性。

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。
