DESCRIPTION OF WORK / BIOSKETCH
My research focuses on understanding the impact of action on perceptual and cognitive function in the human brain. In natural vision and reading, we constantly move our eyes from one target to another for detailed image analysis onto the fovea, the retinal area with highest visual acuity. In doing so, we perceive the world as staying "still", while our brain ignores the abrupt retinal motion and compensates for the repositioning of gaze. Yet, the neuroscience of active vision and reading remains a mystery. What are the neural pathways and mechanisms underlying active perception and cognition? What are the related spatio temporal patterns of brain activity and how are they modulated by eye movements and attention in natural settings? What are the mechanisms of perceptual-motor integration? We currently explore these questions using magnetoencephalography (MEG), electroencephalography (EEG), magnetic resonance and diffusion tensor imaging (MRI/DTI), psychophysics and eye movement detection in real time, with the long-term objective of understanding the complex interactions between visual, language, memory, attentional and motor systems during reading and active vision.
