A typical symptom of Parkinson's disease is tremor in patients. A group of scientists, including Professor Peter Tass from Forschungszentrum Jülich have succeeded in demonstrating the mechanisms which cause the so-called tremor: neuron clusters in the depths of the brain drive the tremor. This discovery supports Tass' research activities aiming at developing a therapy for Parkinson's disease. A new deep brain pacemaker is to bring cells out of the diseased mode for good. http://www.physorg.com/news134987390.html Physics Fri, 11 Jul 2008 09:29:50 EST news134987390
