Research Focus
The Visual and Cognitive Neuroscience Lab investigates how information from audition, emotion, action and cognition influences the visual brain, both in sighted and blind humans.
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 represents information from the rest of the brain. We focus on how visual cortex and eye movements are influenced by information from audition, emotion, action and cognition (see Research Topics). We study these influences mostly in the absence of conscious sight, that is, during eyes closed, during suppression of visual information from conscious awareness and during blindness. Our research on blindness focusses on how the blind brain represents space and information from audition, action, touch, smell and taste.
The lab is currently funded by:
- a PRIMA Grant from the Swiss National Science Foundation (1.5 Mio CHF, 5 years, Principal Investigator: Prof. Petra Vetter)
- a Consolidator Grant from the Swiss National Science Foundation (ERC replacement scheme, 1.75 Mio CHF, 5 years, PI: Prof. Petra Vetter)
- a research grant from the BIAL Foundation (40K EUR, 3 years, PI: Prof. Petra Vetter, Co-PI: Prof. Carolyn McGettigan, UCL).
Petra Vetter co-hosts an international online seminar series on multisensory perception and plasticity, together with Prof. Stephanie Badde at Tufts University. Feel free to join our seminars here: https://www.world-wide.org/Neuro/Multisensory-Perception-and-Plasticity/
Methods
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).
