Directly stimulating the auditory cortex is a potential method of the auditory rehabilitation.For developing auditory cortex prosthesis, an animal model is required to examine the efficiency and safety.Here, we report a cat model for the detection and discrimination of the stimulus parameters.Electrical pulse stimulation on the auditory cortex could evoke a clear behavioral response in the free-moving cats.Based on the ability of the catscognition for the electric stimulus, we make a difficulty try.That is the target is from chl to chx, and the standard is opposite.To our surprise, The discrimination capability of the cats can discriminate them.Spatial summation was observed when current pulses were simultaneously delivered through multiple electrodes.Our results provide a possibility to input sound information directly to the brain by using the electrical stimulation.
