Imaging the cerebellar nuclei in ataxias

Presenter: Dr. Dagmar Timmann

When: 11:00-12:00, Friday, November 18
Where: 109 Cooke Hall


Dagmar Timmann will report on her research of imaging the human cerebellar nuclei in health and cerebellar disease. Susceptibility-weighted imaging (SWI) and Quantitative Susceptibility Mapping (QSM) are used to perform structural
MRI of the cerebellar nuclei at conventional (3T) and ultra-high (7T) magnetic field strength. SWI and QSM data of the dentate nuclei will be presented in different forms of hereditary ataxias including spinocerebellar ataxia type 1, 2, 3 and 6
(SCA1,2,3,6), Friedreich’s ataxia and multiple system atrophy (MSA-C).


Dr. Timmann received her medical degree from the University of Tübingen, Germany. She is a board-certified neurologist. She was a postdoctoral researcher at the R.S. Dow Neurological Sciences Institute (Dr. F.B. Horak) in Portland, at the
Arizona State University, and the Dept. of Physiology (Dr. J. Hore) at the University of Western Ontario, London, Canada.
Dr. Timmann’s research areas are the physiology and pathophysiology of the human cerebellum with a focus on human cerebellar lesion studies, lesion-behavior (“symptom”)-mapping, ataxias, structural and functional MRI of the cerebellum and
cerebellar nuclei. She is an Associate Professor of Experimental Neurology at the Department of Neurology, University Hospital Essen, University of Duisburg-Essen. Dr. Timmann is head of the Ataxia Clinic, Department of Neurology, University Hospital Essen. She is currently vice speaker of the Collaborative Research Center SFB 1280 “Extinction learning” and the Marie Skłodowska-Curie Innovative Training Network "Cerebellum & Emotional Networks“.
