Hi, my name is Verena Nadine Buchholz and I am a PhD student at the Sensorimotorlab since november 2008. My interest for sensorimotor research started while I was working as a neuropsychologist in a neurologic rehabilitation clinic with neglect patients and people with perceptual, as well as motor disorders. Questions like 'How is it possible that neglect can be overcome by vestibular stimulation?' and 'How does the brain actually integrate spatial information across senses?' were intriguing me since then. My PhD research project is therefore about multisensory integration for actions, and as I am interested in the dynamics of these brain processes, my main tool so far has been MEG, which provides excellent temporal resolution and good source localization possibilities. More specifically, the project is about visual and tactile integration for either hand or eye-movements. By studying oscillations I can look at network states corresponding to communication between cortical maps encoding space in different reference frames. I am also very interested in multisensory integration in general, as the brain also makes use of spatial mapping across modalities during perception to achieve more reliable estimates of the real world and sensory predictions. Furthermore, I am very excited about the new possibilities provided by TMS, through which we can actually perturb brain processes with millisecond precision and thereby make inferences about the underlying mechanisms and causal relationships. Keywords describing my research interests are: multisensory, sensorimotor, spatial mapping, timing prediction, spatial prediction, mental simulation, physiological gating mechanisms, BCI for prosthetics
Methods of interest: MEG, EEG, Eyetracking, TMS, EMG, psychophysics
