Dear Alexander,
thank you for your detailed and illuminative response and for offering me a free one-page academic licence for your maximum probability atlas. I might get back to that offer later, after having decided which (probability) maps to use to determine the anatomical locations of the activations we found.
After reading your response, there is one thing that puzzles me though. In all papers that I read, where activations of the prefrontal cortex in fMRI group studies have been found, the loci of these activations were almost always defined by the respective Brodmann areas they (supposedly) reside in. Anatomical regions like the dorsolateral prefrontal cortex, for example, are consistently described as being located in an area that overlaps BA 9 and BA 46.
If refering to Brodmann areas in order to specify the anatomical locations of activations in fMRI group studies is rather imprecise, why is this practice so common in neuroimaging? (I assume not every lab is using probability maps and the use of Brodmann areas in fMRI research predates the invention of those maps).
Thanks again and all the best,
Christian
