Many of the scientific discoveries that are announced these days with
great fanfare often only represent trivial advances in our sum of
knowledge. I can assure you that this is not one of them. Genetics
and molecular biology are two of the most powerful tools that have
ever been assembled to study the human brain - this area of
scientific investigation has scarcely begun.
Because of the integrated design of the brain, there isn't one set
of genes that control personality, another completely different set
that controls resistance to certain diseases, and so on. It's all
one common pool. Coupled with the brain's highly complex and
optimized design, it makes it virtually impossible to determine the
brain's working in health and disease just by looking at such things
as the firings of individual neurons.
There are a whole host of practical questions about the brain that are
lined up waiting for answer - what is the physiological state
corresponding to mania, and how can we stop patients from going into
this state in the first place? - why do some patients with manic
depression not respond to lithium? - what molecular pathways are
involved in the pathogenesis of schizophrenia, and can be interrupted
to prevent its development. Genetics and molecular biology are the
tools which will be used to answer these questions.
There is also a much deeper significance to Cloninger's theory. It
explains correctly exactly the same medical phenomena that Freud set
out to explain, and got all wrong. That almost no one in the world
has even heard of Cloninger's theory 10 years later, let alone has any
idea what it is about represents a massive breakdown in education and
communication in science. On the other hand, it offers incredible
opportunities for those who can convincingly explain this material to
both scientists and the general public.
