Neuroplasticity and Motor Recovery

The human brain is capable of changing its function and structure in response to extrinsic or intrinsic stimuli. This capability of neuroplastic change represents the neurobiological basis for learning new skills or to aid recovery of loss of function in the presence of neurological diseases. The overarching question of our research is: may neuroplastic processes be harnessed for the recovery of sensorimotor function in neurological diseases?

In a translational setting we investigate basic neuroplastic mechanisms of sensorimotor functions in healthy subjects and their modulation in the presence of brain diseases such as stroke or Parkinson’s disease. Different training- and learning interventions are being used and their effect characterized using non-invasive brain imaging techniques (Functional and structural MRI, EEG). We particularly focus on the investigation of neurophysiological mechanisms underlying neuroplasticity-inducing non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) or transcranial alternating current stimulation (tACS). To do this we use neuroimaging and brain stimulation techniques both separately and in combination (tDCS – fMRI; tACS – fMRI).

We collaborate closely with the Day Clinic of Cognitive Neurology at the University of Leipzig and its Outpatient Clinic for Stroke Rehabilitation . To assess the clinical impairment of individual patients we use a comprehensive neuropsychological and sensorimotor test battery, as well as a robot-assisted assessment of upper extremity sensorimotor function using an exoskeleton robotic device.
