Persol, not only variations of where they cut, but what they cut with, the incident angle of the cut, the pressure they apply, how far they cut, horizontally and vertically, and the shape of the cut. Have you ever heard of Forensics?

He was referring to schizophrenic type symptoms, though this may not be what he had in mind.

Even though I've come to expect it from you, but you couldn't be more wrong. Schizophrenia, and many other diseases of the brain, aren't necessarily detectable with an MRI. What can be noted is the loss of brain volume associated with schizophrenia, but this is inconclusive and not all sufferers of it have demonstrable loss of volume. Moreover, some people have normal variations in ventricle sizes (left vs. right). But regardless, it isn't the decreased/increased activity that is discovered with a MRI scan, it?s the volume of the associated ventricle.
If, however, scans are conducted during the performance of abstract reasoning / memory tasks, it is possible to note some excess dopamine activity (Meyer-Lindberg & Berman, 2002). Messenger dopamine is the likely cause of delusion and hallucination and arises deep in the brain at the striatum. Anti-psychotic drugs can suppress this excess dopamine activity and remove the delusions and hallucinations, likely driven by defect in the pre-frontal cortex. But, again, this defect might not be notable if the scan didn't include an abstract reasoning / memory exercise, and this wasn't likely to be looked for prior to 2002.
That's assuming that schizophrenia is the cause, of course. There are many genuine medical conditions often confused with schizophrenia, including Substance-induced psychoses (as a result from ingesting amphetamines, barbiturates, belladonna, cimetidine, cocaine, digitalis or PCP); disease embolism; epilepsy or brain tumors; Creuzfeldt-Jacob disease (CJD); AIDS, syphilis, herpes encephalitis; Alzheimer's disease, carbon monoxide poisoning; deficiency of vitamin B12; tuberculosis meningitis; endocrinopathies -particularly adrenal and thyroid abnormalities e.g. hyperthyroidism; Fahr's Syndrome; Hallervorden-Spatz disease; poisoning from heavy metals e.g. arsenic, manganese, mercury; Humtington's disease, hydrocephalus; metachromatic leukodystrophy; Pick's disease, Cotard's syndrome; Uremia; Wernicke-Korsakoff syndrome and Wilson's disease (Johnstone, 2000). To name a few.

Skinwalker, how about reading the text you are quoting:
Where does it mention schizophrenia?
Where does it mention schizophrenia?
Perhaps I read it wrong, but I'm referring to an ongoing discussion within the thread itself, but to clarify, I've edited my post. Thanks for pointing that out. The changes of my post above are either the addition of quotes or the bolded text in the first paragraph.

you mentioned schizophrenia many times before did you not? or am I out of context?
Nebu, I indeed did, but not in the actual text Skincrawler initially quoted. So yes, you are out of context.
With regards to schizophrenia being detectable by MRI - Please read this article:

UCLA Press Release - Monday, September 24, 2001
UCLA brain researchers using a powerful new technique have created the first images showing the devastating impact of schizophrenia on the brain. The findings, published in the Sept. 25 issue of the Proceedings of the National Academy of Sciences*, show how a dynamic wave of tissue loss engulfs the brains of schizophrenic patients in their teen-age years.

Btw, I know it says mice, but just think these sort of "scans" might be done through other methods.
Persol, you dunce, I did not say mental problems should show up on an MRI scan, I said a disease of a brain, like schizophrenia should. There are other methods one employs to gauge for psychological dysfunctions. Your contention was, these abductees are psychologically impaired. In which case they they should exhibit symptons of of this impairment. Yet, John Mack, professor of psychiatry at Harvard, is publically saying the abductees are psychologically normal.
So do I go with you senseless and unsubstantiated doubts, or with, John Mack, whose had the opportunity to test the subject.
