Scientific topic: Neural basis of subjective visual experience
Field of Research
My research focuses on the neural bases of higher-level visual functions like attention, visual awareness and Gestalt perception. To better understand how visual perception works I use bistable stimuli. Such stimuli contain ambiguous visual information, causing perception of the observer to switch spontaneously from one of the possible interpretations to the other without any physical stimulus change. They provide an excellent experimental tool for studying higher-level perceptual functions such as selection, grouping, disambiguation and filling in the missing information. While people view these stimuli, I study their brain activity with main neuroscience tools available for healthy humans: fMRI, EEG, TMS, tDCS.
Recently I also got interested in the methodology of high-resolution structural and functional MRI of the human brain (at the magnetic fields >3 Tesla), hoping that better spatial resolution will help us better understand the mechanism behind higher-level visual functions.
