Initially yes, but new drugs are based on the findings of neurobiology
- a reductionist approach to the brain/mind. New receptors are
targeted, or the affinity and/or selectivity for a receptor known to
be important is improved.  No-one just throws them at patients and
watches anymore.

Its only wild if you don't want it to be true.  Of course current
drugs are relatively blunt tools for changing the mind of a patient,
but they do work and IMHO the targets of the drugs must therefore be
involved in how the mind arises from the brain. (Its just empirical
observation!) By your comments do you mean that you don't believe that
dompinergic, glutamatergic and all the other systems in their
particular anatomical forms are enough to account for the mind?

Fine, but that just shows it is the orchestration of all these systems
that forms the mind.

:) becuase she doesn't believe anything needs adding, its all there in
the brain for us to investigate.  At least she hasn't added a
dualistic aspect
