Scientists at the University of Wisconsin-Madison have grown human embryonic stem cells into neurons that appear capable of adapting themselves to the brain's machinery by sending and receiving messages from other cells, raising hopes that medicine may one day use this tool to treat patients with such disorders as Multiple Sclerosis, Parkinson's and amyotrophic lateral sclerosis, commonly known as Lou Gehrig's disease.
Researchers inserted the human cells into the brains of mice where they successfully integrated themselves into the wiring. Then the UW team applied a new technology, using light to stimulate the human cells and watching as they in turn activated mouse brain cells...
