Significant advances have been made in our quest to understand the human brain. Among the different structures and functions of the brain, the visual brain and visual function are probably the best understood, yet some of the basic questions still remain unanswered. Our group is currently working on the following questions:
- Where is the bottleneck that limits spatial and temporal visual resolution?
- What determines access to visual awareness, and what is the functional role of awareness?
- How does the visual system resolve ambiguities?
- What is the function of visual attention?
- How does the brain combine different visual features to generate a coherent perception?
We use both psychophysical and brain imaging methods.
