Nicolas Schweighofer, PhD




1540 Alcazar St., CHP 155,
Los Angeles, CA 90089-9006


Dr. Nicolas Schweighofer’s research focuses on neuro-computational models to understand the neural bases of motor learning. This includes investigations into motor plasticity in the cerebellum, cortical map plasticity and reorganization in the sensorimotor cortex, multiple task learning, and adaptive decision-making during motor learning in healthy and lesioned brains. Predictions are tested through behavioral and/or brain imaging (fMRI and TMS) experiments at USC and with international collaborators. He aims to optimize relearning of motor skills in patients with stroke.
