For the first time, an international group of researchers led by the German Center for Neurodegenerative Diseases (DZNE) and the Bonn University Hospital has proven the existence of such signatures for motor

Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they were able to show that individual experiences influence the development of new neurons, leading to measurable changes in the brain.
