Lasse Christiansen

Senior Researcher

Research Interests

My research interest circles around sensorimotor control, motor learning and in particular central nervous plasticity. Through brain stimulation and electrophysiology, I have explored neural processes underlying motor skill learning and recovery of sensorimotor functions following CNS lesions. Recently I have been working with non-invasive plasticity protocols targeting the injured spinal cord. I have a strong interest in identifying determinants of individual variability in motor control, motor learning and response to non-invasive brain stimulation
