Results: 1 The analysis revealed that GAP-43 immunopositive neurons in rats were localized in all the layers of lateral geniculate nucleus and the layers II -VI of visual cortex area 17,and GAP-43 is stained by a ring and dot figure and brown-yellow colour in cytomembrane ; 2, In the critical period, gene expression concentration and number of GAP-43 immunopositive neurons, in both the lateral geniculate nucleus and the visual cortex area 17, received from the deprived eyes, are reduced.

结果：1、GAP-43在正常大鼠视觉系统表达主要见于外侧膝状体全层和视皮质17区Ⅱ—Ⅵ层神经元胞膜中，呈环状或点状棕黄色免疫阳性反应；2、在敏感期内剥夺眼对侧外侧膝状体和视皮质17区GAP-43表达的免疫阳性神经元染色变淡(P＜0.05)，且免疫阳性神经元数目减少(P＜0.05)。

GA often uses C or Visual C++ to compile codes, so the program is not only long and cockamamie but also the efficiency is low and the velocity is slow. This paper uses software Matlab powerful calculating ability and many functions to compile programs, then encapsulate and link those programs to run without Matlab environment. At last use Visual C++ friendly alternate function to compile in-out interface.

针对遗传算法常用C或Visual C++编写源代码，程序庸长繁琐，效率不高，运行缓慢的特点，本文采用Matlab强大的数值计算能力和众多的库函数编写算法；然后封装和链接程序，使Matlab编写的算法能够完全脱离Matlab的编程环境；利用Visual C++良好的人机交互功能，用Visual C++编写算法的输入输出接口界面。

In allusion to the above-mentioned problems, considering the self-adaptive regulative ability of the visual system to natural perceptive information and the feedback between visual cortexes, a bidirectional NNSC model is proposed, which is based on the robust principal component analysis and the priors of receptive fields of simple cells in V1. And using the (Polak-Ribiere-Polyak) PRP conjugate gradient descent algorithm, the minimum optimization problem of the objective function can be realized.
