Some useful notations and definitions are give in this chapter.In Chapter 2,a class of discrete-time model of two-cell cellular neural networks with symmetric temptate are investigated. We obtain some results about the stability,asymptotic stability,the existence and attractability of 2-periodic solutions.

近年来大量的实验结果表明，视皮层下的外膝体神经元和视网膜神经节细胞都具一定程度的方位和方向敏感性，这些性质是遗传决定的，不受后天环境的影响。

In this paper, we introduced the method and set of cat perceptual learning and research the character of orientation discrimination and contrast detection of cat, and we also research the effect of visual perceptual learning on the response of the Dorsal Lateral Geniculate Nucleus neuron with the method of single-neuron in vivo recording techniques, by which to the ends of knowing the mechanism of neuron in the perceptual learning. Perceptual learning in orientation discrimination and contrast detection was first observed by psychophysics method in cat in the following two experiments.
