Our Cognitive Neuroscience group is interested in the mechanisms that drive human behavior. We focus on the question how complex brain networks are set up and try to understand how temporal properties of brain function orchestrate neural computation in these networks.
Our research focuses on the speech production network and involves basic research but also studies on clinical conditions. Speech constitutes a highly social behavior that allows studying functional loops which integrate feedforward and feedback information. We are particularly interested whether the temporal properties of sensorimotor processes contribute to lateralization of speech production. We currently test our predictions derived from functional imaging experiments of healthy volunteers in patients suffering from brain tumor or Parkinsonís disease. Our basic research questions contribute to the understanding of pathophysiology and recovery mechanisms in the studied pathological conditions and may hopefully translate into better therapeutic approaches.
