In our daily lives, we are bombarded with a stream of rapidly changing visual input. Yet, when studying brain representations, stimuli are generally presented in isolation. Here, we studied the representational dynamics of human vision using a combination of fast stimulus presentation rates, EEG , and multivariate decoding analyses. Using presentation rates of 5 images per second, we were able to obtain the representational structure of a large number of stimuli, and showed the emerging abstract categorical organisation of this structure. In a second experiment, we replicated these results and explored how varying the presentation rate affects the amount of processing for individual stimuli. These results show that the combination of fast stimulus presentation rates and multivariate decoding analyses has unprecedented potential for studying the temporal dynamics of information coding in the human visual system.
