Parkinson's disease brain surgery. Close-up of surgeons implanting electrodes for deep brain stimulation (DBS) of areas of the brain in a patient with Parkinson's disease. The electrodes provide continuous electrical stimulation, which blocks the signals that cause the tremors characteristic of Parkinson's disease. This operation is being carried out by a team led by Professor Stephan Chabardes. Photographed at the Centre Hospitalier Universitaire Grenoble, Grenoble, France.
