OBJECTIVE: To investigate the effects of moderate hypothermic CPB with a hemodilution on hippocampal bcl-2 and bax gene expression and neuronal apoptosis in rats.

目的：旨在研究中度低温、血液稀释体外循环对大鼠海马bcl-2和bax基因表达及神经元凋亡的影响。

Objective To explore the effect of hepatic growth factor on the neuronal differentiation of the neural stem cells.

目的 观察肝细胞生长因子对神经干细胞向神经元细胞方向分化的作用。

Proofs that when iterating with the BP algorithm, if one of the neural units fall into saturation regions at least, and the other one at least don't, then the condition number of the Hessian matrix of the error function is very larger.

证明了BP算法在迭代过程中，如果至少有一个神经元落入饱和区而同时至少有一个没落入饱和区，则目标函数的Hessian阵的条件数变大，这是导致"网络瘫痪"现象的原因，也是BP算法收敛速度慢的主要原因。

Heterotopia, simply defined, means a collection of neurons in an abnormal location, due to an arrest in migration.

灰质异位，简单的定义就是由于迁移障碍导致神经元位于异常的部位。

Heterotopia is the name given to focal or diffuse collections of ectopic neurons in the cerebral hemispheres, a neuronal migrational anomaly.

皮质异位是指大脑半球的局限性或弥漫性神经元异常迁移，可以分为室管膜下、皮质下以及带状异位

In rats, prenatal carmustine exposure produces loss of lamination in cortical structures and distinct nodular heterotopia, which are prone to hyperexcitability of neurons and may contribute to the increased seizure susceptibility observed in these animals.

采用给孕鼠腹腔注射卡莫司汀的方法可制作广泛型皮质发育障碍模型，组织学显示皮质层状结构消失，海马CA1区形成灰质异位结节，这些病理改变易引起神经元的过度兴奋，导致癫痫易感性增高。

Then, based on the random opening and closing of ion channels, we consider the random HH model.

首先，在确定论模型中，研究发现温度的增加不利于神经元动作电位的产生。

Second, we study the effect of noise in the information code of HH and FHN neuronal systems.

其次，我们以FHN和HH模型为例研究了在神经元信号编码过程中噪声的影响。

In Chapter 2, for the HH neuron, the intrinsic dynamical features and the general rules in information processing are studied in detail.

第二章重点研究了HH神经元的本怔动力学特性以及其在信息处理中的一些动力学机理。

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。
