Artificial and real nerve cells linked

Small step
could pave way
for easing neurological ills

By Alan Boyle
MSNBC

Oct. 7 - Using $7.50 worth of electrical parts, scientists hooked up an artificial neuron with biological nerve cells extracted from a lobster. The resulting neuron network transmitted signals back and forth just like the real thing - one small step toward a bionic future.


RESEARCHERS AT the University of California at San Diego suggested that their experiment could eventually open the way toward techniques to restore neurological function in patients suffering from maladies such as stroke or Alzheimer's Disease.

"We built an electronic neuron that is able to work as a member of a neural framework," said physicist Henry Abarbanel, director of the university's Institute for Nonlinear Science. "It's science fiction, except that we did it."
However, an expert in neurobiology cautioned that it would take "beyond 25 years" to apply such technologies to human health.

"What they're doing is pioneering work on a small scale, but it's probably premature to say that it's going to have any impact on health" said Terry Sejnowski, director of the Computational Neurobiology Laboratory at the California-based Salk Institute and an investigator with the Howard Hughes Medical Institute.
