Although auditory inattention has been described in man, little is known of the anatomy of the lesions which produce this inattention. In experimental animals, auditory inattention or extinction has not been produced outside the frontal lobes. In this study, auditory, visual, and somatesthetic inattention has been produced by discrete lesions in the caudal portion of the inferior parietal lobule and both banks of the caudal portion of the superior temporal sulcus in four experimental monkeys. In three control monkeys with lesions in the temporal lobe, this defect was not seen. (24:323-325, 1971)

Key Words.—  Auditory extinction; auditory neglect; auditory simultaneous stimulation; parietal ablation; sound localization.
