Re some recent messages concerning integrated approaches to studying
the brain, I wanted to give an example of a successful integrated
approach. While it is obviously heavily based on neuroscience in
some areas, it goes far beyond neuroscience.
This approach has gone from explaining why some psychiatric patients
have so many apparent physical symptoms (somatization - a subject
that interested Freud early on) to an overall theory of personality
and its relationship to psychiatric disorders. Furthermore it is now
showing the way to "the astonishing hypothesis" that many important
physical diseases originate in the brain as a result of dysregulation
of the body's defense and repair mechanisms (possibly even cancer and
atherosclerosis).
The brain's central role as the processor and coordinator of the
body's response to all threats to the body's survival are also
becoming apparent. The key evolutionary pressure would be an
unsuccessful attack by a predator that results in an infected
penetrating bite wound with extensive blood loss. Humans rarely face
this type of threat today, but all mammals reflect this evolutionary
history.
Evolutionary or "Darwinian" medicine is just beginning to emerge as a
discipline - the ultimate impact on science and medicine promises to
be revolutionary.
An introductory reading list follows. Remember - this "page" is
still under construction, as they say on the Internet. Some of the
most basic scientific details are still being filled in - it was just
this last month that reports on the specific mechanisms underlying the
"flight or fight" response and glucocorticoid suppression of immunity
appeared in Science. Many more details will be filled in as a result
of the Human Genome Project.
