Re: Is there a corralation berween brain-activity and extra-intro-verts?

Dear Mikael,

Hello!  The only recent literature I have been able to find on this general 
topic consists of 2 articles by JG O'Gorman in the journal Biological 
Psychiatry vol. 19:95-136, 1984: "Extraversion and the EEG:  An evaluation 
of Gale's hypothesis."  These authors were unable to confirm any 
correlation between brain activity and personality type, partly because of 
variability in defining the exact type of personality any one person was 
likely to have.  I feel that such a simple hypothesis correlating brain 
activity with a complex phenotype like personality is only a starting point 
and cannot be really accurate.  Even with a major behavioral-personality 
disorder like autism, differences in brain function between control and 
affected individuals are still being sought and there are many disputed 
findings.  For a good review of this topic see "New hints into the 
biological basis of autism" in Science, vol. 294, pp. 34-38, 2001--article 
by Erik Stokstad--you can look up a summary of this article at the NIH site 
called www.pubmed.gov.
