My current research focuses on (i) vision during eye-movements as well as on (i) multisensory representations of spatial and motion information in the primate brain. Given that we make eye-movements more often than our heart beats, we aim to understand if and how visual perception is modulated by various classes of eye-movements. In addition, we are concerned with the interplay of the visual, auditory and tactile senses for the perception of space and self-motion.
In our studies we combine neurophysiological recordings in the animal model with behavioral and fMRI/EEG-studies in humans. Most recently, we have started a collaboration with the local university hospital to investigate disturbances of spatial and motion processing in neurological and psychiatric patients.
