Most neuroimaging manuscripts that employ fMRI will have one or more nice looking brain renderings showing, at the minimum, some basic statistical contrasts between conditions that establish which brain regions tend to be more (or less) active during some condition, compared to a contrast condition. These are useful for establishing that your experimental conditions are reasonable, even if the contrasts in question aren't particularly interesting. Of course, if you are showing contrasts for experimental manipulations that haven't previously been shown, then these contrast maps are going to be quite interesting, and it will be important to provide brain renderings that clearly illustrate the point you are trying to make.

There are many ways to create these brain renderings, depending in part on which software package you used to run your analyses in the first place. This wiki entry walks you through the steps of calling up a particular statistical analysis carried out in SPM and rendering the results and saving the renderings to bitmap files (PNG formatted files) using MRIcron.
