This paper analysis the motion effects on human visual system.By using electroenc ephalogram (EEG) and gammo- amino butyric acid (GABA) we prove middle temporal area (MT) are sensitive on motion perception. It links the bridge between LGN(lateral geniculate nucleus), V1(Primary visual cortex) and MST (medial shlerior temporal area), the feedback between these area are paraelle and circular. Nearly all neurons in MT area show their preference on the specific motion direction and angle. The instantanous firing rate at the specific phase is 10 times higher than other phases at a certain neuron. The neurons that react similar response to a certain kind of features can compose a neuron cluster and work synchronously. The contribution of us is to simulate a computational motion field model, which can refelect the neuron activities in MT. This model can explain the attention selection mechanism and visual perception to some extent. However, further endeavor should be addressed on the interconnection and correlation of neurons.
