Cautions for fMRI Researchers – evidence that dead Salmon produce some brain activity may start correction and re-checking fMRI studies. Hopefully, all advances in this area will produce greater evidence that can be relied upon for how neural activity can be studied in more depth.
As summarised by Neuroskeptic, “…but not everyone uses multiple comparisons correction. This is where the fish comes in – Bennett et al show that if you don’t use it, you can find “neural activation” even in the tiny brain of dead fish. Of course, with the appropriate correction, you don’t. There’s nothing original about this, except the colourful nature of the example – but many fMRI publications still report “uncorrected” results”
