Field of Research

Our lab studies higher level visual perception in the human brain. One fundamental question is the "binding problem": how do the segregated visual pathways combine information of colour, motion, and depth to provide a coherent visual percept? We use illusions, high-resolution imaging and binocular rivalry paradigms to gain insights into neural processes involved in conscious perception. Second, we try to understand where and how the brain encodes the 3D-spatial layout of our environment. This is tightly coupled to visual motion induced by ourselves or by objects around us. We thus study the coding of complex visual motion trajectories that inform us about our own heading, or - through perspective changes - about the space around us. Finally, we study the rich social and emotional information conveyed by motion in faces.

Methods

fMRI and EEG for localization and connectivity estimation in the human brain. Neuronavigated Transcranial Magnetic Stimulation (TMS) to disturb perception, attentional processes and associated decision making. Virtual Reality, natural movies and binocular rivalry as stimuli. Classical statistics and pattern classification algorithms for de-coding information in brain areas.
