Transfer ability of monkey M to different stimuli after the second (bilateral) ST cortex lesion. Also shown are the transfer levels attained by monkey M in an earlier study. The acoustic stimuli of Test 1 were the HT (3676 Hz) and a Gliss tune ranging in frequency between 1437 and 8333 Hz. In Test 2, the stimuli were an alternating (0.7 Hz) HT and LT (243 Hz) and a steady MT (947 Hz). The tempo difference between the stimuli used inTest 2 was eliminated in Test 3 by using alternating (4 Hz) doublets of the HT and LT and a pulsating (4 Hz) MT.
