A new two step 2 D motion detection model is presented.A 1 D multi velocity motion detection layer is constructed based on the 1 D velocity detection feature of MIVD.A multi velocity 2 D motion perception can be achieved by means of the good construction feature of cellular neural networks(CNN) to emulate the local dynamic interactions of cortex function columns.The experiment shows that this parallel and layered multi velocity model is good at early vision motion perception.By using the model,the attention...

A new two step 2 D motion detection model is presented.A 1 D multi velocity motion detection layer is constructed based on the 1 D velocity detection feature of MIVD.A multi velocity 2 D motion perception can be achieved by means of the good construction feature of cellular neural networks(CNN) to emulate the local dynamic interactions of cortex function columns.The experiment shows that this parallel and layered multi velocity model is good at early vision motion perception.By using the model,the attention focus mechanism based on “motion information drive” can be realized,and the model can also be used as a part of “objective drive” mechanism in high level feedback of vision system.

提出了一个新的两阶段二维多速度运动检测模型.该模型首先利用基于乘积侧抑制速度检测子MIVD的一维速度检测特性,构成了一维多速度运动感知层.检测出一维速度信息,然后利用胞神经网络(CNN)模拟皮层功能柱间的局部动态交互,完成多速度二维运动检测.实验证明,这种分层并行多频道模型是对初级视觉运动感知的良好建模.应用这种模型可以实现基于“运动信息驱动”的注意力集中机制,也可用于构成视觉高层反馈的“目的驱动”机制.

The research compared attention deficit hyperactivity disordered (ADHD) boys with normal boys in vision-motion. The ADHD boys of 10 to 13 years old are significantly lower than the normal boys on the setting-figure test, eye-hand coordinating test, vision tracing test and figure canceling test, showing that ADHD children's level of vision-motion are significantly lower than the normal children. Moreover, the ADHD boys' field independence is lower significantly than the normal boys, showing that ADHD...

The research compared attention deficit hyperactivity disordered (ADHD) boys with normal boys in vision-motion. The ADHD boys of 10 to 13 years old are significantly lower than the normal boys on the setting-figure test, eye-hand coordinating test, vision tracing test and figure canceling test, showing that ADHD children's level of vision-motion are significantly lower than the normal children. Moreover, the ADHD boys' field independence is lower significantly than the normal boys, showing that ADHD children's level of psychological function differentiation are significantly lower than normal children. And these two groups are not different significantly on length estimation.

10岁到 1 3岁男性ADHD儿童在镶嵌图形、眼手协调、视力追踪和数字划销等视觉—动作实验上的分数显著低于同一年龄段的男性正常儿童 ,显示ADHD儿童的视觉—动作能力比正常儿童差。ADHD儿童与正常儿童相比 ,知觉方式的场独立性较弱 ,心理机能分化程度较低。ADHD儿童在长度估计实验上没有发现异常

· AIM: Using functional magnetic resonance imaging, to inspect visual cortex physical reactions stimulated by rotating grating, and to its components.· METHODS: On 1.5T MR scanner, GRE-EPI imaging sequence was carried on 9 h discover ealthy volunteers, the visual cortex response data were processed after delinearation by SPM99.· RESULTS: Different components of rotating grating excited different areas of the visual cortex. Dramatic response in the central part of the occipital lobe, which was related to white light stimuli, located at primary visual cortex. Response area in bilateral Broadaman 19 areas was related to vision-motion function. And weak response area in the central part of the occipital lobe was related to shape perception. · CONCLUSION: Rotating grating conclude plenty of visual information, and it excites different areas of the optic center as a stimuli. fMRI is a valuable equipment to study the physiology of visual cortex.·

目的:利用功能磁共振成像技术,观察旋转光栅刺激引起的视觉皮层生理反应,探索其反应的组成成分。方法:在1.5T磁共振扫描仪上,对9例健康志愿者以梯度回波基础上加平面回波(GRE-EPI)成像序列法采集旋转光栅引起的视皮层反应数据,SPM99软件进行数据离线后处理。结果:旋转光栅的各种刺激成分引起不同视觉皮层中枢的兴奋。枕叶中央区域的强烈反应位于初级视觉皮层区,与白光刺激有关;两侧19区的反应与视觉运动功能有关。枕叶中央微弱反应区与形状察觉功能有关。结论:旋转光栅包含丰富的视觉信息,作为刺激源可兴奋视觉中枢的不同区域。功能磁共振成像技术可以作为研究视皮层生理的良好工具。
