Research Focus

The Visual and Cognitive Neuroscience Lab investigates how information from audition, emotion and cognition influences the brain processes that create our visual perception of the world.

Human visual cortex is often thought of as mainly processing information arriving from the eyes. However, research from our lab and others has shown that visual cortex also receives and represents information from the rest of the brain. The aim of our research is to find out how visual processing is influenced by non-visual information and how this affects our visual perception. We focus on auditory, emotional, predictive and cognitive influences on vision (see Research Topics). In addition, we investigate whether these influences on visual processing occur on a conscious or unconscious level, and in the presence and absence of sight (e.g. in blindness).

The lab is currently funded by a PRIMA grant from the Swiss National Science Foundation (Principal Investigator: Prof. Petra Vetter) and by a research grant from the BIAL Foundation (PI: Prof. Petra Vetter, Co-PI: Prof. Carolyn McGettigan, UCL).

Petra Vetter co-hosts an international online seminar series on multisensory perception, together with Prof. Stephanie Badde at Tufts University. Feel free to join our seminars here:


We employ a range of methods from cognitive neuroscience: fMRI (including multivariate pattern analysis and retinotopic mapping), eye-tracking, psychophysics (continuous flash suppression, binocular rivalry, dual-task paradigms), psychophysiology (fear-conditioning, skin conductance response), transcranial magnetic stimulation (TMS).
