In our research, we aim to understand how different parts of the central nervous system interact to generate purposeful behaviors. In particular, we study how the cerebral cortex and the basal ganglia interact in order to control motor actions, both under normal conditions and in individuals afflicted by Parkinson’s disease

In our previous work we have studied motor control functions, ranging from relatively simple circuits in the spinal cord [1] to elaborate networks like the cortico-basal ganglia-thalamic loop in healthy brains and in models of Parkinson’s disease [2–6]. To this end we have developed unique technologies that allow us to analyze neuronal activity from 10-20 brain structures in parallel in freely behaving animals [7].
