We don't flinch (well, perhaps a little) at the
thought of having cardiovascular implants like
pacemakers, stents, and valves placed inside our chests
to fix our broken hearts. We attach ourselves to
dialysis machines, ventilators, colostomy bags and
telemetric devices in order to stay in the game. So why
do we shy away from implants that can revive or work
around an injured or diseased nervous system by
electrically stimulating the nerves or muscles?

As James Cavuoto explains in his report, "Neural
Engineering's Image Problem," the answer isn't simple.
For one thing, the controls for these nerve-stimulating
devices, while shrinking in size, are still "black
boxed" and worn outside the patient's body. For another,
the quality of life they can restore to the patient is
often limited. Perhaps there are also unfortunate
associations from popular culture. How many of you think
the word "cyborg" has a positive ring to it? When
reading the words "electrical stimulation" and "nervous
system," how many of you see Dr. Frankenstein screaming,
"It's alive!"
And then there is the problem of getting the case for
neural prostheses and electrical nerve stimulation heard
above the clamor of biotechnology's proponents. Who
wouldn't like to have "natural" biological methods for
repairing the devastation of stroke and accident-induced
paralysis, or the genetic misfiring of neuromuscular disease?
But whatever the case, the fact is that functional
electrical stimulation devices work right now and are
getting better all the time. As you can see from our
photo of implant recipient Jennifer French, with her
broad, beautiful smile, these devices have the ability
to restore function, mobility, and independence. Further
down the road, probably a lot further, they may even
become part of a larger biomedical tool set that will be
used to enhance our physical and mental abilities. They
deserve a second look from those who thought they were
only good as interim solutions or bioengineering
curiosities.
Serious Fun at FIRST

As the Rover robots clambered over the Martian
surface and sent back tantalizing evidence of
ancient water there last month, thousands of high
school students were gearing up for the regional
finals of the FIRST (For Inspiration and
Recognition of
Science and
Technology)
robotics competition. The brainchild of Dean Kamen,
medical devices inventor, sultan of Segway, and
archetypal maverick genius, the FIRST competitions
aim to use robots to fire up high school students
worldwide about science and technology. Participants
build robots that compete in a "sports event"
complete with frenzied, costumed fans and half-time festivities.
But FIRST is not just about building machines.
It's about building teams and increasing community
interest in technology. Competitors are judged, of
course, on the versatility and endurance of their
robots, but also on their own abilities to work
together. They are encouraged to bring other
students into the mix and get their schools'
neighborhoods involvedin much the same way that a
football team might raise money by putting on a car
wash or might promote athletic activity by running a
sports clinic for younger kids.
There has been a lot of discussion about the whys
and wherefores of technology education. How do we
get more young people to sign on? The inspiring
regional FIRST matches that took place in March
suggest that leading by example is a great way. In
addition to the squads of rambunctious robogeeks,
thousands of grown-ups—parents, teachers,
engineers, machinists, software guys,
friends—worked alongside the students in the robo
pits or cheered wildly from the stands. They were
engrossed and engaged, and they certainly gave off
the impression that being a nerdy techie could also
be way cool. Get involved
(http://www.usfirst.org) at the
grass roots. The FIRST Frenzy 2004 championship
event is this month at the Georgia Dome in Atlanta.
It's seriously effective. And seriously fun.
