Hi Fatima, As Bruce mentioned, this is a poorly defined region. Within the PFC, what exactly are you measuring? DLPFC or some the whole of the PFC? If you are interested in evaluating DLPFC, my suggestion would be to manually draw it yourself on the fsaverage (as Bruce mentioned) and map it onto every individual subject.
Hope this helps, rahul > Hi Fatima, > > it's kind of a poorly-defined region, so I'm not sure how to answer. > Those labels don't make up all of prefrontal cortex.
