Throughout the course of history it has always been noted that any ideas
about brain function depended upon the highest technological model of
the day. Hence, in the Greek or Roman era the ventricular system was
singled out because of the devel- opment of hydraulics. Early in this
century we drew the analo- gy between telephone circuits and the brain.
Now it is popular to characterize neural function as that of a
sophisticated com- puter. Indeed, in many ways it may be. But, as yet,
the pre- pared human brain will likely prevail in the sorting out of
information necessary for a proper diagnosis. In this manual, POECK has
provided the ground work for such prepara- Dr. tion. We all admire the
clever diagnostician, and usually ascribe the skill to great intuition.
Not so! It is the clinician who has seen many patients, and has compiled
a menu of choices. Dr. POECK is such a clinician, and he has provided us
with his menu of choices. Use of these lists will likely aid the student
or resident physician in coming to a proper diagnosis but, more
importantly, will help train his or her mind to think in a logical and
systematic way. ROBERT J. JOYNT, M.D., Ph.D.
