Human
Brain (and Senses) Reported in Boston
By Larry Malone
Sometimes
you need a third eye to penetrate dense subjects and see them
clearly. That current ran through the week-long FOSS middle
school workshop on the campus of Northeastern University in
Boston the second week in July. The main attraction was the
Human Brain and Senses
Course. Susan Brady, Linda De Lucchi, and Larry Malone
had the luxury of almost enough time to thoroughly present
the course to an enthusiastic assemblage of middle school
educators from around the country. The primary goals of the
workshop were to prepare the participants to teach the course
confidently to students and to act as Human Brain and Senses
staff developers. The secondary goal was to look beneath the
surfaceany surfaceto explore deep truths.

Last
fall at an NSTA convention we mentioned the idea of a Human
Brain and Senses workshop to Marilyn Decker and
Pam Pelletier of the Center for the Enhancement of Science
and Mathematics Education program (CESAME). They discussed
how great it would be to hold the workshop on their campus.
They were particularly excited because they are affiliated
with the CenSSIS (Center for Subsurface Sensing and Imaging
Systems) engineering center on their campus and saw an opportunity
to bring the CenSSIS expertise into the workshop plan.
CenSSIS
has a number of high-powered engineering research centers
as members, including the optics lab on the Northeastern Campus,
Woods Hole Oceanographic Institution, and Massachusetts General
Hospital. Each of these engineering groups was engaged in
looking below the surface of something to find out whats
going on. Marilyn and Pam immediately made the connection
between the diverse interests of the CenSSIS groups and the
challenges of studying the brains structures and functions
without disturbing its integrity. Their enthusiasm was enough
to convince us that Boston was the place for the workshop.
We started planning.
The
results are history now. The workshop started on Sunday afternoon
with a get-acquainted reception and dinner at the Boston Museum
of Science. After introductions, we steered the group to the
human body wing, where we explored brain physiology, optical
illusions, reaction time, depth perception, etc. A fine supper
and a show in the IMAX theater about Ernest Shackeltons
Antarctic adventure wrapped up the first day.

Monday
and Tuesday we tackled the course, covering the first six
investigations. We also had a short stint in the computer
lab to become familiar with the CD-ROM and a quick tour of
one of the laser research labs on campus. We saw exploratory
systems for looking under Earths surface for land mines
and some emerging technologies for 3-D imaging of human joints
and microscopic imaging of the cell interiors. Amazing stuffthe
third eye in action.

Wednesday
we took a trip to Woods Hole to see some emerging technologies
for imaging the sea floor. We visited the prototype of the
latest ROV (remotely operated vehicle) called ABE, short for
autonomous benthic explorer. What makes ABE the cutting-edge
imager is that it is unmanned and untetheredit is able
to go anywhere in the ocean and work for as long as it is
needed.
Thursday
afternoon we took the T (Bostons underground transit)
to Mass General Hospital, one of the largest and most important
medical research hospitals in the country (14,000 employees!).
Our host, George Chen, took us behind the scene to see the
proton knife. This experimental tumor killer uses a proton
beam to destroy cancer cells by damaging their DNA or producing
a flood of free radicals that do the job. The heart of the
knife is a modest cyclotron connected to a mammoth beam-aiming
system, all of which weighs in at some untold number of tons.
All this technology is designed to deliver a high dose of
energy at a precise location without any damage at all to
surrounding tissue. A considerable breakthrough.
Friday
we wrapped up the course and parted company, somewhat brainier
and quite a bit more sensitive to the tools used to study
our amazing our brain and senses.
