I'm currently reading this paper:
Savic & Lindström (2008). PET and MRI show differences in cerebral asymmetry and functional connectivity between homo- and heterosexual subjects.
It certainly is an interesting study but I just can't understand what the benefit is of mapping PET data on MRI scan images instead of doing fMRI scans. Any ideas what the benefits are?
Also, I found out that reference 64 is referenced in the text but missing in the reference list. I was thinking that PNAS is peer reviewed...
All right then, any feedback is much appreciated.
