In this paper, we introduced the method and set of cat perceptual learning and research the character of orientation discrimination and contrast detection of cat, and we also research the effect of visual perceptual learning on the response of the Dorsal Lateral Geniculate Nucleus neuron with the method of single-neuron in vivo recording techniques, by which to the ends of knowing the mechanism of neuron in the perceptual learning. Perceptual learning in orientation discrimination and contrast detection was first observed by psychophysics method in cat in the following two experiments.
