    Many thanks - appreciate the kind words. Thanks also for always working to work with care in your science. It makes all the difference. Among other challenges, when we first submit…

    Yeah, it did prove to be a rather one-sided conversation... ;)

    Many thanks! It was a ton of fun. Hard to beleive that we are coming up on 20 years since the data for the salmon was first collected...

    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 w…

    When we published the salmon paper, approximately 25-35% of published fMRI results used uncorrected statistics. For myself and my co-authors, this was evidence of shaky science. Th…

    That was our paper! We showed that you can get false positives (significant brain activity in this case) if fMRI if you don't use the proper statistical corrections. We did win an …

    As the first author of the salmon paper, yes, this was exactly our point. fMRI can be an amazing tool, but if you are going to trust the results you need to have proper statistical…

    As the first author on the salmon paper, yes, that was exactly our point. Researchers were capitalizing on chance in many cases as they failed to do effective corrections to the mu…

    Pretty much what TeMPOraL said. You can scan pretty much anything with fMRI and find results if you don't use proper statistical corrections. I have found "significant" voxels in a…

    > we have a print of the poster on our lab's wall That's amazing - you made my day with that statement. I left neuroscience for the software world back in 2012, so I don't have a l…

    I'm the first author of the salmon fMRI paper, if you have any questions. Generally, how the investigators do their statistics can lead to implausible conclusions. Extraordinary cl…

    I've scanned about 300 people as part of my research career. The director of the imaging center reviewed every anatomical scan. From that group of 300 we informed about three peopl…

    Marc Abrahams, organizer of the Ig Nobels, asked us for a salmon recipe to include in a cookbook they were publishing. We sent in a single page recipe for how to cook a salmon in a…

    My wife and I are so irritated about this. She bought a Cricut Maker last year to make masks for friends and family. Custom images were cut for every person she made a mask for. No…

    As the first author of that paper, I approve of this link.

    I cooked it for dinner. We kept it cold in the snow outside the building all day while we worked. Tasted like regular salmon when we ate it.

    We just had the one salmon to scan, unfortunately. Regardless of the pre-existing condition of the salmon (zombie, rust, etc) there were no significant voxels of activity once we a…

    Good question. Ultimately, in fMRI we are looking for changes in the local ratio of oxygenated to deoxygenated blood. As neurons begin firing in a brain region more oxygen-rich blo…
