Using Magnetic Forces to Control Neurons, Researchers Find Brain is Vital in Glucose Metabolism

New York, NY (Scicasts) — To learn what different cells do, scientists switch them on and off and observe what the effects are. There are many methods that do this, but they all have problems: too invasive, or too slow, or not precise enough. Now, a new method to control the activity of neurons in mice, devised by scientists at Rockefeller University and Rensselaer Polytechnic Institute, avoids these downfalls by using magnetic forces to remotely control the flow of ions into specifically targeted cells. Jeffrey Friedman, Marilyn M. Simpson Professor and head of the Laboratory of Molecular Genetics, and colleagues successfully employed this system to study the role of the central nervous system in glucose metabolism. Published online today in Nature, the findings suggest a group of neurons in the…
