In addition, a new kind of discriminative features derived by muli-layer perceptrons will be addressed.

另外，还将讨论一种基于神经元网络的可分别性特征的应用。

ABSTRACT］ Objective To observe the effects of α-MSH on gastric distension sensitive neurons in rat dorsal vagal complex.

目的 观察α-促黑色素细胞激素对大鼠背侧迷走神经复合体胃扩张敏感神经元放电频率的调节作用。

The difference of discharge frequency of sensitive distention neurons, before and after distention, was not significant.

微量注射9 g/L NaCl前后胃扩张敏感神经元放电频率的改变差异无统计学意义。

Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上，在半复平面上给出了蛋白质序列的非退化的2-D图形表示，同时利用复向量的主要特征—模和相位，给出了蛋白质序列的一种数值刻划，进一步在3-D空间里，把20种氨基酸分别分配给正12面体的20个顶点，根据正12面体的对称性得到了20种氨基酸的3-D表示，进而得到了蛋白质序列的3-D图形表示和对应的数字序列，并利用图的不变量和数字序列的特征比较了9种动物的神经元

ObjectiveTo establish a feasible method of culture and purification of embryonic dorsal root ganglion neurons of rats.

目的：建立一种切实可行的胚胎大鼠背根神经节神经元培养及纯化方法。

The hyperexcitability of spinal dorsal horn neurons is one of the main reasons for persistent pain.

脊髓背角神经元超兴奋性被认为是病理性疼痛发生的重要原因。

Objective:To study the changes of 5-HT in nucleus raphe dorsalis in gerbils after cerebral ischemia and reperfusion.

摘 要：目的：探讨沙土鼠脑缺血时中缝背核神经元5-HT的变化。

Methods:ABC methods of immunohistochemistry and image analysis technique were used to study the changes of 5-HT in nucleus raphe dorsalis after cerebral ischemia and reperfusion in different time.

用免疫组织化学ABC法及图象分析对沙土鼠脑缺血不同时间以及缺血10分钟后再灌不同时间其中缝背核神经元5-HT的变化进行研究。

RESULTS: Cells were spindle shape before induction, obviously varied following preinduction, and then the body began contracted after being induced in the medium for 1 hour, with the presence of a few small orbicular-ovate or spindle cells. Following 24 hours of induction, about 60% cells became double pole, multipolar or cone shape, showing neuron-like structure.

结果：①诱导分化前呈梭形细胞，在加入预诱导培养基后未出现明显的形态变化，换用诱导培养基1 h，胞体开始收缩，出现少数较小的卵圆形或纺锤形细胞，诱导24 h后，约60%细胞变成双极形、多极形和锥形，出现类似神经元细胞的形态。

The two classes of rat DRG neurons have their own characteristics of firing.

大鼠DRG两类兴奋性神经元各具不同的放电特征。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
