Feedback oscillatory traveling waves and perceptual biais

Brain oscillations in response to visual stimulation have been shown to travel across the cortex. In this project, we combine behavioral psychophysics with MEG recordings to investigate how feedback traveling waves influence perceptual bias. Our project uses a bistable apparent motion paradigm to encourage communication between visual areas and to generate expectations about stimulus properties. We investigate a) how expectations based on temporal or spatial context bias the perception of a target stimulus presented along the apparent motion path and b) whether the communication between areas that is necessary for the task takes the form of traveling waves.
