For the bottom-up attention process, areas of interest that deserve visual attention are formed by a sequentially extracting of feature map, conspicuity map, and interesting map. Firstly, based on Treisman's feature integration theory and the characteristics of orientation and frequency selective nerve cells in biological cortex, we propose a new 2D optimal quadrature filter in the meaning of minimum energy loss to extract intensity, edge, orientation, symmetry, curvature and comer features to form the feature maps. Then based on the local competent and global cooperative perception character of biological vision, we design a kind of competent/cooperative filter and use a set of such filters to extract conspicuous locations that will most likely to cause visual attention from feature maps to form conspicuity maps.

我们根据Treisman〓的特征整合理论，结合生物视觉皮层的方向、频率敏感性神经元，提出采用一组调制在不同尺度和方向上的新的最佳正交特征滤波器并行地提取图象的亮度、边缘、方向、对称性、曲率和角度等特征作为注意线索，构成特征图；在此基础上，基于生物视觉的局部竞争和全局协作特性，本文设计了一种竞争协作滤波器用于从特征图中提取可能引起视觉注意的显著位置构成显著图，各显著图进一步通过本文提出的融合算法和非线性松弛迭代算法生成自底向上兴趣图。

So, endomycorrhiza was formed betweenD. candidum roots and strain AR-15. There were several nucleoli and nuclei in thecortical cells next to exodermis when a nucleus transfer across the cell wall wasobserved. Sometimes plant roots were damaged by strain AR-15. The microstructure of D.

真菌AR-18倾向于根生长，在根周围形成了一个包围圈，由根被细胞侵入外皮层通道细胞及其相邻的皮层细胞，然后向其他皮层细胞推进；真菌菌丝也可由皮层细胞侵入外皮层细胞。

The spinal cord, report Gaillard et al.1 in the current issue. Although the grafting of tissue to the brain has been explored as a strategy forrepairing the injured nervous system for over 100 years2, the current paper1 demonstrates a remarkable and complex set of long-distance,topographically appropriate axonal projections to a variety of targets distributed throughout the nervous system.

Gaillard等在当前的杂志中报告了放置入损伤的成年小鼠的运动皮质的胚胎皮层的移植物，令人震惊的是，它恢复了投射向远到脊髓的靶区的排列。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。

Thus, salicylate is widely used for studying the mechanisms of tinnitus. The aim of the present study was to investigate the effects of salicylate on voltage-gated sodium, potassium and calcium channels in the inferior colliculus and the auditory cortex neurons by use of the whole-cell patch clamp method, in order to obtain insight into the relations of tinnitus and voltage-gated channels.

The mechanisms underlying these biases of subcortical neurons are still under investigation.

视皮层内较强的方位、方向选择性主要是由视皮层内部机制形成的，而皮层下神经元也具有明显的方位、方向敏感性，并对视皮层神经元的方位、方向选择性有初步的贡献，然而这种皮层下方位、方向敏感性的形成机制仍在进一步的探索中。
