How conscious experience is realized in neuronal activity is one major unsolved problem in science. Neuroscientists have focused on finding human neural correlates of consciousness for over two decades. Here I go beyond this correlational paradigm and use fMRI to investigate the causal relationship between cortical activity and visual awareness. First, I will demonstrate that a change in visual awareness of a constant visual input can lead to changes of neural activity in visual cortices. Second, conversely, I will show that neural activities that immediately precede stimulus presentation can bias/predict the contents of visual awareness during binocular rivalry. These findings go beyond mere correlates of consciousness to reveal candidate areas that are causally involved in realizing conscious experience.
