    It appears that there may be bugs in the statistical software used to derive results from fMRI scans

    Interesting article, @user9876. Its about resting state fMRI, which is where you measure blood oxygen uptake patterns when a person is "at rest" (lying in darkness). They found one particular type of analysis - clusterwise analysis - didn't correct very well fro multiple comparisons.

    So this means that we should be cautious about studies reporting group differences on resting state fMRI when the study uses clusterwise analysis. Otherwise, its business as usual.
