Computer modeling still requires animal research
While
searching for evidence of the necessity of animal research in the medical
field, I came across a video
at Brainfacts.org, called “Research
Questions and Technique”. This video addresses some of the alternatives to animal research. In the
video, researchers Michael E. Goldberg MD and Sharon L. Juliano PhD are
interviewed regarding the various possible approaches to conducting medical
research. Both Dr. Goldberg and Dr.
Juliano acknowledge that medical research data can be obtained using computer
modeling, but it is not as simple as turning on the computer and clicking the “run
simulation” button. Dr. Goldberg put it
this way, “Computer modeling requires data.
In order to understand our data, we often have to get help from computational
neuroscientists, but they can’t do
anything without us. You can’t model
data if you don’t know what the data is.
And so biologist, who work in wet labs, who work with organisms, who
work with cells, who work with behaving animals, provide the data so that
computational neuroscientists can help us understand.” What he means by this is that computer modeling
is built by people who rely on data obtained by people who conduct the hands on
research, which includes animal research.
In a nut shell, computer modeling depends on animal research. Dr. Juliano put it this way, “Data (computer)
modeling is a very important tool that we can use in conducting research, but
data modeling has a limited set of inputs and outputs, and when we do data
modeling, we always have to bring it back to the real organism, to the real
cell, or the real animal in order to understand if that (computer modeling result)
is something that has worked.” What she
was saying is that computer modeling, although a legitimate research tool, is
still very limited in its complexity.
The results from those models still must be verified in the real thing. Dr. Juliano also added that while conducting
a set of experiments on a cell culture, it yielded very different results than
when they conducted the same experiments on the same cells on an intact animal.
“So you needed the whole animal in order to have the proper response…..I think
it’s very important to understanding how we do research and why using a whole entire
animal is important.” Cell cultures just
do not produce the same results as when the whole animal is used and so the
information obtained from cell cultures is limited by comparison.

This particular post is of great interest to me, especially regarding my topic of animals in space. Many of the space experiments I have come across have used animals as a test bed for research. I was hoping to determine if advancements in technology, such as sensors and programming, could make this role for animals obsolete. However, per the information present here, it seems that this is not the case. Since computer modeling alone may not yield accurate results for a real world example, perhaps animals are doomed to maintain their role as test subjects for humanity's scientific research.
