Abstract

On the basis of previously published data, a neuronal scheme of organization of the visual perception in the cerebral cortex, is suggested. An idea of neuronal module is introduced: a cylinder of cortical neurons whose receptive fields are directed towards the same area of the visual field and respond to different spatial frequencies and orientations. A system of overlapping modules is able of piece--wise Fourier--description of portions of the image. The modules of the Clare--Bishop area are composed of receptive fields of different size. Owing to that each neuron of the module projects inhibitory influence upon other neurons, the module acts as a filter picking out the texture. Therefore, the modules of the Clare--Bishop area single out and supply Fourier--description of subimages, the latters being characterized by the same local spectrum within their own limits. The lower portiön of temporal cortex performs a rough identification of subimages and images with the aid of systems of learning neurons. The parietal cortex conforms the description from temporal cortex to the complete description in the modules of occipital cortex, thus performing the transition from an image to a concrete picture.

摘要

基于先前发表的数据,提出了大脑皮层视觉感知的神经元组织模式。引入了神经元模块的概念:一个皮层神经元柱,其感受野指向视野的同一区域,并对不同的空间频率和方向做出反应。重叠模块系统能够对图像部分进行逐段傅里叶描述。克莱尔 - 毕晓普区的模块由不同大小的感受野组成。由于模块中的每个神经元对其他神经元施加抑制性影响,该模块起到了挑选纹理的滤波器作用。因此,克莱尔 - 毕晓普区的模块挑选并提供子图像的傅里叶描述,这些子图像在其自身范围内具有相同的局部频谱特征。颞叶皮层下部借助学习神经元系统对图像和子图像进行粗略识别。顶叶皮层将颞叶皮层的描述与枕叶皮层模块中的完整描述相匹配,从而实现从图像到具体画面的转换。
