fMRI methods and statistics have advanced quite a lot since the dead fish days, that critique does not really hold up today.

While I would agree that the prevalence of the problem has been minimized in fMRI during the last 15 years, I disagree that our critique does not hold up. The root of our concern was that proper statistical correction(s) need to be completed in order for research results to be interpretable. I am totally biased, but I think that remains worthwhile.
