Dr. Steve DeWeerth is a member of the Laboratory
for Neuroengineering. He has been collaborating with
Emory researchers through a joint
program. DeWeerth and Dr. Richard Nichols at Emory currently
have graduate students that are doing research at Georgia
Tech and Emory in multidisciplinary fields combining biology
and electrical engineering disciplines.
These students are trying to understand how locomotion
works by looking at spinal cords of rats and examining how their
locomotion circuitry works. They do this by examining a rat's spinal
cord and they also build electrical devices to simulate spinal cords
(see photo). The experiments require wet lab time at Emory followed
by electrical data analysis time at Georgia Tech. As the student
collects more data and moves into the latter stages of their PhD,
they spend more time at Georgia Tech but need to train newer students
at Emory. Coordinating this can be challenging.
There are two training issues that are critical.
One issue is scheduling a training session where two students agree
that they will do an experiment together and one will guide the other
through the process. The second issue is being able to quickly interrupt
someone with a question that needs an immediate response. |

A demo is being put together to try and address both
issues. Georgia Tech and Emory are connecting a dedicated point to
point 1Gigabit Ethernet connection from the Nichols lab in the Whitehead
buidling to the DeWeerth lab in the Whitaker building.
A compressionless video application will be used over this high bandwidth
connection to help a student at Tech remotely train a student at
Emory. The hope is that the two students will not have travel time
and this can facilitate more frequent training sessions. We also
hope that a 24 hour accessible video connection that is has low jitter
and latency will be appealing and lend itself to natural conversational
collaboration. It was made clear that sometimes the student only
needs a quick question answered to finish an experiment. Supporting
a way to interrupt an expert briefly and then move on is highly desired.
Once the demo is performed, we would like to not only
assess whether the two issues outlined are handled or improved in
any way but also how this untraditional network solution performed.
Is this the right way to handle these obstacles? Will it becomes
transparent to the researchers so that they can focus on their research
rather than deal with the technology beneath? We will continue to
ask these questions as we observe.
Because there are many pieces to this demo, it will
be important to look at all of them to see what is successful and
what might need improving. There is a network, a cutting edge application,
and a change in process in the lab. Is it one of the things, all,
or none that make a difference to the research progress? As we learn
how to answer that question, with the help of the researchers, we
will design a combination that best benefits them.
Currently, equipment
is ordered and we await installation. A progress report will posted
when available.
