Research Background:
Motor imagery, Neurofeedback, Electroencephalography (EEG), Functional magnetic resonance imaging (fMRI), Motor and cognitive assessment, Stroke patients

Repeated practice of movement sequences enables these movements to be learned and perfected. A similar effect can be achieved by simply imagining these movements, since the activity of the responsible brain areas strongly overlaps. This type of motor imagery (MI) training allows especially motor impaired individuals (e.g., stroke patients) to work on improving their actual motor skills on a cognitive level and is therefore promising in the context of neural rehabilitation. To provide feedback on performance during practice, additional neurofeedback (NF) can be provided based on individual brain activity during practice, often EEG-based. This allows for real-time objective error analysis as well as correction so that neural activity is specifically modulated.

Current Project: In this across-subjects multiple baseline study, extensive testing of motor function and cognition as well as structural and functional imaging using EEG and MRI will be performed before and after four weeks of MI-NF training. The aim is to further investigate the effects of intensive home-based MI-NF training on the connectivity of motor and prefrontal areas and on the recovery of upper limb motor function in stroke patients.

Research Background:

Current Project: Research on neural oscillations has shown that impaired midfrontal theta activity (4-8 Hz) is associated with cognitive symptoms in patients with Parkinson’s disease. By transcranial alternating current stimulation (tACS) cortical oscillations can be modulated and thus cognitive processes and behaviour. The aim of my PhD project is to investigate tACS as a potential therapy to restore cognitive functions in Parkinson’s disease.

Research Background:
Transcranial temporal interference stimulation (tTIS) is a new method to non-invasively stimulate
regions in the depth of the brain. The idea behind this is to send out two very-high frequencies that do not interfere with brain activity, which are slightly different (e.g. 2 kHz and 2,1 kHz) and are overlapping in the region of interest (ROI) in deep brain regions such as the basal ganglia. In this way, the frequencies extinct each other with only the delta of both frequencies (in this example 0,1 kHz) targeting in the ROI. This frequency then stimulates the deep laying regions. Overlying cortical layers are not affected by this technique. The current is applied by electrodes which are placed on the scalp of the participants. Previous studies demonstrated the efficiency of tTIS in an animal model and the safety of tTIS in humans. The studies of this application extent the research question to a proof of principle of tTIS in a disease model namely Parkinson’s disease (PD).

Current Project: In this project, tTIS will be applied for the first time in PD patients. One major symptom complex are the motor symptoms, which are caused by neuronal oscillation changes in the basal ganglia, namely the putamen. Another aspect of this disease are non-motor symptoms like apathy, which is defined by a lack of motivation. This is thought to be caused by changed oscillations in the region of the nucleus accumbens.
To provide an exact stimulation, we will simulate the stimulation on a single-subject level with individual MRI scans. In the second phase, the two different aspects of this disease are investigated. First, we stimulate the putamen of the participants. The change in motor performance will be measured with a finger tapping task, which is analyzed by a 3D video camera system. Another sequential finger tapping task is performed to measure motor learning. Second, the nucleus accumbens will be stimulated with a gamma frequency to enhance effortreward behavior and therefore modulate the motivation. This is tested with a well-established motivation task, in which the participants have to squeeze a hand grip to gain rewards. The studies will be accompanied by a standardized safety investigation. Using a cross-over real or sham design, the impact of tTIS on motor and non-motor symptoms will be investigated in order to perform feasibility, safety and a first prove of concept of tTIS to treat motor and non-motor aspects of a neurodegenerative disease.
