Abstract

We would like to thank Dr. Harold Schuknecht for his comments and criticisms of the article entitled, "Long-term Partial Eighth Nerve Section in Cats."

1. It has been shown that frequency (pitch)-intensity discriminations in animals has not been affected following peripheral (Elliott,1 Elliott and McGee2) or central lesions (Neff3; Butler et al4; and Raab and Ades5) of the auditory system.

However, the aim of the present experiments was to investigate the loss of "pattern" discrimination as a result of peripheral lesions. The tone patterns were selected on the basis of the studies by Diamond and Neff in their cortical ablation experiments. They found that, following bilateral cortical ablations of the auditory areas, the animals lost their ability to make pattern discriminations, whereas they could still perform the frequency and intensity discrimination to tones. We believe, as did Diamond and Neff in their experiments, that
