Comments on: fMRI and behaviour – Neuroskeptic clears things up http://bodyinmind.org/fmri-and-behaviour-neuroskeptic-clears-things-up/ Research into the role of the brain in chronic pain Tue, 07 Feb 2012 09:36:16 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Neuroskeptic http://bodyinmind.org/fmri-and-behaviour-neuroskeptic-clears-things-up/#comment-4166 Neuroskeptic Tue, 23 Mar 2010 22:30:27 +0000 http://www.bodyinmind.com.au/?p=3131#comment-4166 Thanks for the link! That EEG study looks kosher to me from a brief look, although the Vul et al non-independence error can certainly be a problem in EEG (and PET, MEG, any neuroimaging technique) as well as in fMRI. Problems arise whenever you measure activity at many different points in the brain, and then focus in on the parts where the biggest effects seem to be occurring. If you then do statistics on those parts without taking into account that you've selected them specifically because you saw big effects there... you might end up in error. Thanks for the link!

I love studies like this. The correlation problem highlighted in the Vul article, and explained by Neuroskeptic does not apply here as they are using EEG rather than MRI and as such are have far fewer comparisons to deal with. From the looks of things (in my humble opinion etc) they have performed a reasonable and fair statistical analysis. Fascinating findings, someone should blog on it! Thanks Anne Marie.
