How is it relevant now? Please expand. Sure its relevant in the sense that fmri requires multiple tests, and that has to be accounted for correctly, but we do so now...with greater and greater accuracy as newer and newer techniques take hold, mind you, for a statistical problem that is very difficult to model. The salmon experiment showed that the thresholds scientists used at the BEGINNING of neuroimaging science were insufficient...this is a new field, methods take time to develop.The salmon experiment is not relevant now because we are not making the same mistakes we made then, over a decade ago.
