IMHO "brain scans" are not quackery but how they are represented can be.
In a scan like Dr. James Fallon (low frontal lobe activity) he could be impulsive and absent minded but not psychopathic. It all depends how the imaging data is normalized and interpreted. Also the PET scan doesn't show connective activity between neurons.
