Research group and research interests
Dagmar Timmann, MD, Associate Professor
The motor control Dagmar Timmann’s group is interested has a long-standing interest in the physiology and pathophysiology of the human cerebellum. A major interest is the involvement of the human cerebellum in different forms of motor learning. We are interested in the contribution of the cerebellum to acquisition and extinction processes. Questions addressed are whether the cerebellum is involved in particular forms of learning, which cerebellar areas are involved and what the mechanisms of cerebellar involvement are. Another interest is the role of the cerebellum in cognition.
A main focus is the study of patients with defined cerebellar pathology. Localization of focal cerebellar lesions and extent of atrophy in cerebellar degeneration are defined based on high-resolution structural MRI. Lesion data is correlated with findings in neurophysiological and psychological experiments. In addition, functional MRI studies are performed using 3T and 7T MR scanners. Transcranial direct current Non-invasive brain stimulation (tDCS) is used to modulate cerebellar function in healthy subjects and patients with cerebellar disease.
