The steady-state visual evoked potential: Basics and recent applications to object recognition

A visual stimulus flickering at a specific frequency elicits an oscillatory response of the cortex, which has the same temporal frequency as the initiating stimulus. In human EEG this response is known as SSVEP. The SSVEP approach has a long-standing tradition as a tool for investigating fundamental visual processes and visual attention. During the last years, we applied the SSVEP method to higher-object recognition research. Furthermore, the SSVEP can be used to separate brain responses elicited by the constituting elements of a visual display by tagging them with different frequencies. We made use of this advantage by starting to investigate the neuronal correlates of rather complex scene perception. The talk will provide you both with theoretical and practical information about the SSVEP method and with a variety of studies demonstrating its application to object recognition research.
