Our results showed that the total dendrite branch length and arborization of hippocampal neuron were not affected by the inhibition of ASICs for a short time, while the total dendrite branch length was reduced and dendrite development was impaired if ASICs were inhibited for a long time.It suggested that ASICs play a role in the dendrite development,which may help understand how ASICs affect the formation of neuronal networks and participate in higher brain fuctions such as learning and memory.

结果发现短时间抑制ASICs的功能并不影响海马神经元的树突总长度和分支，而长时间抑制ASICs的功能则会降低树突总长度，影响树突的发育，表明ASICs参与调节树突的发育，这将有助于理解酸敏感离子通道如何影响神经网络的形成，并进而参与学习记忆等高级脑功能。

Baxter, working on cats under experimental conditions comparable to ours, however, reported that intravenous injection of adrenalin either had no marked effect or a slightly augmentative effect on the histamine-induced secretion, and that stimulation of the splanchnic nerve yielded similar results.

若用较长的间隔如每10—30分钟收集一次胃分泌，则此双相效应就会被掩盖，因而得出肾上腺素对猫胃分泌无明显效应或有增加分泌的效应的结论，如Baxter等人所得到的一样。在急性实验中，刺激大内脏神经对组织胺引起的猫胃分泌有显著的抑制效应。与肾上腺素的效应不同，刺激大内脏神经的效应通常是单相的。

Radiolabeled pharmacological binding assay showed: 1 BmK AS bound specifically to a single class of non-interacting binding sites on both rat brain and cockroach nerve cord synaptosomes with high affinity and low low capacity. The association of BmK AS with both synaptosomes was quick to reach equilibrium, but the dissociation seemed to be only partial. The specific binding of BmK AS was independent of membrane potential, and couldn't be modified by veratridine. Moreover, the binding of BmK AS could be inhibited by native BmK AS, BmK AS1, BmK IT2 and BmK IT on both synaptosomes, but not or partially inhibited by BmK Ⅰ and suggesting BmK AS type neurotoxins might bind to a distinct receptor site on mammal and insect sodium channels with a similar manner from β-scorpion toxins.

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。
