视觉形成的神经机制

Neural mechanism of vision

外界信息的 80 %～ 90 %是经视觉系统传入大脑 ,因而研究视觉形成的神经机制具有十分重要的意义。从视网膜内的信息传递、视觉通路、视觉信息在中枢的逐级抽提和平行处理以及视觉系统的可塑性等几个方面进行了较全面的综述 ,以了解视觉形成的神经机制。

of all information was transferred to brain by visual system.So it is very important to study the neural mechanism of vision.The retinal neurocircuity,visual pathway,hierachical hypothesis,parallel processing and plasticity were reviewed in present paper to investigate the neural mechanism of vision.
