 Scientists have used magnetism to activate  tiny groups of cells in the brain, inducing bodily movements that  include running, rotating and losing control of the extremities -- an  achievement that could lead to advances in studying and treating  neurological disease. 
The technique researchers developed is called magneto-thermal  stimulation. It gives neuroscientists a powerful new tool: a remote,  minimally invasive way to trigger activity deep inside the brain,  turning specific cells on and off to study how these changes affect  physiology. "There is a lot of work being done now to map the neuronal circuits  that control behavior and emotions," says lead researcher Arnd Pralle,  PhD, a professor of physics in the University at Buffalo College of Arts  and Sciences. "How is the computer of our mind working? The technique  we have developed could aid this effort greatly." Understanding how the brain works -- how different parts of the organ  communicate with one another and control behavior -- is key to  developing therapies for diseases that involve the injury or malfunction  of specific sets of neurons. Traumatic brain injuries, Parkinson's  disease, dystonia and peripheral paralysis all fall into this category. The advances reported by Pralle's team could also aid scientists  seeking to treat ailments such as depression and epilepsy directly  through brain stimulation.
