Just a few fibers are enough for the two hemispheres of the brain to communicate with each other. This was shown by a new international study led by Professor Dr Michael Miller (University of California, Santa Barbara) and Professor Dr Lukas J. Volz (Department of Neurology at University Hospital Cologne and the University of Cologne’s Faculty of Medicine) in close collaboration with Professor Dr Christian Bien’s team at the Bethel Epilepsy Centre (University Hospital OWL at Bielefeld University).
