Ladder Beam
The human mind is a complex area of study, even with advances in
research technology, scientists have yet to discover a good portion of
how the brain functions. Dr. Gerlinde Metz, an assistant professor at
the University of Lethbridge, took a simple approach to her complicated
area of study, inventing the Ladder Beam to aid her in her research. The
device was designed to test animal movement in an experiment at a Swiss
university, but its uses have since expanded to include a wide array of
neurological studies.
Dr. Metzs invention is a horizontal ladder with metal rungs that can be
positioned in a specific order. Lab animals, such as mice or rats, are
trained to walk across the ladder. When the rungs are placed at regular
intervals, the animals are able to anticipate their next step. When the
rungs are rearranged to create irregular distances, the animals may have
greater difficulty crossing the structure and scientists are able to
observe how they react to the changing variable.
Though the ladder beam is not patented, it has proved to be an
invaluable tool for scientists around the world. By observing its
effects on lab animals, researchers are able to better understand limb
coordination, skilled movement and walking in humans as well. These
observations have the potential to lead to new therapies and treatments
for spinal cord injuries, Parkinsons disease and other neurological
disorders.
