Research Interests

A better understanding of neural characteristics and determinants of physiological movements, motor development and motor control in healthy humans, and delineation of the pathophysiology of movement disorders are the main themes of our group. We study healthy children and adults, and both paediatric and adult patients with movement disorders and neuropsychiatric diseases of all ages using different methods including psychophysical paradigms, classical experimental neurophysiology, transcranial magnetic stimulation (TMS), electroencephalography (EEG), and structural and functional magnetic resonance imaging (MRI). In our Gilles da la Tourette syndrome research team we focus on inhibitory control, neural correlates of premonitory sensations, echophenomena, and attentional as well as perceptual processes related to tic generation.

In multi-modal genotype-(endo)phenotype neurophysiology-imaging studies we explore network characteristics in basal ganglia-thalamo-cortical and intracortical circuits in patients with genetically determined parkinsonism and dystonia including PARKIN-, PINK1-parkinsonism, X-linked dystonia parkinsonism (DYT-TAF1), and dopa-responsive dystonia (DYT-GCH 1). We study motor network abnormalities in different monogenic isolated and combined dystonias. Also, we have a special interest in understanding motor network abnormalities in other rare movement disorders including ataxias, myoclonus and paroxysmal disorders. We are involved in clinical studies in patients with Tourette syndrome, Huntington disease, multi-system atrophy, spasticity and cerebral palsy.

Our team comprises neurologists, neurophysiologists, psychiatrists, psychologists and study nurses. We are particularly interested in interdisciplinary research bridging different clinical disciplines including neurology, psychiatry, paediatrics and human genetics, and neuroscience. We offer different research perspectives both for neuroscientists and clinicians to embrace personal preferences and scientific perspectives.

Statistical parametric maps showing increased activation in the left somatosensory cortex in healthy controls compared to Tourette patients in the Go condition of an S1-S2 Go/NoGo
paradigm. Voxels significantly more activated in controls than in patients during Go trials are overlaid on a single-subject surface rendering (Thomalla et al., Brain 2014).

Self-reported urge intensity (red curve) and bouts of tics (grey lines) of a representative Tourette patient across a 5-minute free ticcing session. Lines underneath the x-axis indicate occurrences of bouts (boxed line), the first tic of each bout (blue vertical lines), and the last tic of each bout (green vertical lines). B-D: Cross-correlograms of urge intensity (±SEM) and single tics (B), urge intensity and the first tic within bout (C) and urge intensity and the last tic of a bout (D). E: Mean time lag between urges and bout onset (first tic, blue) and offset (last tic, green). Boxes show 25-75th percentile, whiskers show min to max (Brandt et al., Cortex, in press).

Short-interval intracortical inhibition (SICI) of XDP patients and healthy controls determined with transcranial magnetic stimualtion. SICI at conditioning pulse intensities of 70%, 80%, 90%, and 100% active motor threshold (AMT) is shown. The mean motor evoked potential
(MEP) size (+SEM) is given as a percentage of the unconditioned test pulse. SICI is significantly increased in XDP patients at a conditioning pulse intensity of 100% AMT (Weissbach et al., Mov Disord 2015).
