Here is the pertinent reference in DeMarse's paper: http://www.jneurosci.org/content/23/28/9349.full.pdf+html
Now to answer what you asked me about. Do I think what DeMarse did is morally right or wrong? I do not want to pass judgement because I am still in school and don't have to worry about funding my own research. A professor I respect for his scientific integrity told me every scientist has a skeleton in their closet (referring to research projects). I think the fact that DeMarse's paper caught on like wildfire just goes to show you that a majority of Humans (computer programmers included) can be relatively stupid.
