It was suggested:(1) A strikingly strong sensitivity to eye gaze is observed from birth, and eye gaze perception is key to the development of language capabilities and social cognition;(2) The neural basis of gaze perception is the superior temporal sulcus, which is heavily connected with the amygdala implicated in processing emotion, and the STS is an important part of a wider network for social cognition neural systems;(3) Processing on early stage of eyes gaze cueing reveals specific event-related potential component;(4)The eyes gaze cueing effect has been labeled reflexive and likened to orienting in response to peripheral cues, however, it lasts longer;(5) The gaze cueing effect is influenced by many different facets, from lower level configural aspects such as face orientation to higher level cognitive factors. Furthermore, the gaze cueing effect reveals significant sex difference in normal adult population.

And we used them into the inspection of these polluted gases. We used them because the constringent speed of wavelet neural network is very fast, they are not sensitive to the inputs of the network and they have the characteristic that they also can effectively approach the functions or signals. Classical neural networks mostly train the network with back propagation algorithm.

Third, it has a discussion on the development of modern and traditional artificial neural network technology and their application in image processing. It summaries that the model of the Pulse-coupled neural network based on Elkhorn's model of the cat visual cortex was constructed according to the mammalian vision systems. The nonlinear modulation property, which is a generic and pervasive biological pulse-coupling mechanism, is used in the construction of PCNN. So, PCNN finds many applications in image processing, including segmentation, edge extraction et al. As all known, the performance of the image segmentation depends not only directly on the adjustment of PCNN parameters and the statistical properties of image but also on the cyclic iteration times N of PCNN. If the parameters have been properly set, it turns out to be essential to select a suitable criterion to determine N.

回顾了神经网络技术的现状，指出传统人工神经网络只利用了生物神经元有限的属性进行模型构建，而90年代产生的脉冲耦合神经网络充分利用了哺乳动物视神经网络特有属性，其神经元模型除了考虑生物神经元特有的线性相加、兴奋与抑制属性外，还考虑到生物神经元特有的非线性相乘调制耦合特性；考虑了哺乳动物视神经系统视野受到适当刺激时，相邻连接神经元同步激发产生35Hz～70Hz振荡脉冲串特性等，所以PCNN网络模型更靠近真实生物视觉特性，特别是哺乳动物视神经网络，特别适合计算机图像处理应用，尤其在生物细胞图像分割、图像平滑、降噪及图像中目标的分类、计数等方面的研究。
