Average responses of the brain to repetitive tone bursts were obtained by CAT, a kind of digital computers. Results were as follows: 1) The typical waveform consisted of positive, negative and positive components.The peak latency of the initial positive one lay at 100msec or more and total duration of the response were about 400msec. 2) Under deep mintal anesthesia the response became less clearer and often disappeared. 3) The threshold of the average response was estimated at less than 30dB in 1KC. 4) The response to tone bursts was abolished by white noise simultaneously given. 5) The minimal interval to evoke average response was examined and at least 1 sec was found to be needed. These results were discussed in a view of previous investigations.
