A Spatial Temporal Integration Model of Primary Visual Cortex Concerning Directional Selectivity
Vision is the most crucial function with which human beings interact with the environment, and visual information accounts for more than 80％ of the total information that human receive from the outside world. The investigation of the mechanism of visual processing is closely correlate with brains other functions like learning, associate memory, abstract thinking and so on. The research on the receptive field (RF) is an important component of exploring the brain mechanism of processing visual information. Recently, more and more interests have being put into the modulating effect exerted beyond classical RF. It is assumed that the modulating effect based on horizontal connectivities and higher cortex feedback might involve with contextual processing of visual representation. In this article, we proposed a simplified spatial temporal integrating model of primary visual cortex concerning directional selectivity, via simulation on the sequences of continuously changing gray scale images, we assumed the plausible contribution of the spatial temporal integration in suppressing noises and correctly representing the motion information of moving scenes.
