It was a really crude way of getting at things, but they would get a high-tone part of the cochlea one place and low-tone another place and concluded that there was a primary area, secondary area here, another kind of an area back here. Anybody that works on auditory area in cats knows that this has been changed radically, and the whole concept of an AII is still there in cats but practically no place else, and it was based on a misinterpretation of the data and so on. But it did not really matter for the lesion studies because you took everything out anyway. Basically cats are trained to go from one side of a box to another and what could we do after the lesion. And every time, after the lesion, whatever you trained them to do, they did not do it, but they would re-learn, and this is one of the problems we have with lesion studies because when an animal re-learns a task after a lesion, have they re-learned it in a new way, or have they recovered the ability to do it in the way they did before – and why did they loose it in the first place?
