A new study by neuroscientists at the German Primate Center (DPZ) – Leibniz Institute for Primate Research in Göttingen shows that our brain deals with different forms of visual uncertainty during movements in distinct ways. Depending on the type of uncertainty, planning and execution of movements in the brain are affected differently. These findings could help to optimize brain-computer interfaces that, for example, help people with paralysis to control prostheses or computers with their thoughts alone (Nature Communications).
