  • Vision & Consciousness


In visual perception, the ultimate goal is to understand how we see anything. We do not understand what visual consciousness is and most of visual processing appears to be unconscious. The first step in understanding these questions is to investigate the differences between conscious and unconscious states of visual processing. As one example, we use electrical stimulation of the human brain in epileptic patients (temporary electrodes due to clinical reason only) and investigate causal links between brain areas and perception.


  • Statistical processing in Vision

Our environment contains lots of redundant information. Given the limited capacity of our visual system, it is important to process this massive information efficiently and economically. One example of this efficient processing is the automatic statistical analysis of a visual scene. Our lab investigates the mechanism of statistical processing in the brain, particularly focusing on the computation of the mean size of objects in visual arrays.
