Psychological results in reactions to tone before and after extirpation of the temporal lobes.

Abstract

Examined the reactions to tones before and after extirpation of the temporal lobes. A German dog was trained to take meat at a low tone and refrain from it at a high one. Then, his temporal lobe was removed, and after 3 days rest, training was continued. After a good response was established, the right temporal lobe was removed. It was observed that the reactions were now slower, but gradually the ability to differentiate the high tone from the low one returned. Thus, the location of the act was in the cortex outside the extirpated temporal lobe. Concluded that after extirpation of both temporal lobes, a dog has the ability to react differently to different tones, and can be taught new associations.
