Detection of Motion Direction Specific Response Using Steady-State Visual Evoked Potentials

Abstract

Noninvasive methods for probing direction-selective neuronal activity are effective for understanding human motion perception. Some previous works using the Steady-state Visual Evoked Potential has used adaptation to reveal direction-specific activity. Here we present a method that reveals motion mechanisms directly through a signature predicted by the motion energy model: motion energy detectors produce opposite-signed responses to phi and reverse-phi stimuli.
