The immediacy and directness of our visual experience belies the complexity of the underlying neural mechanisms, which remain incompletely understood. Recent neuroimaging studies suggest that activity in ventral visual cortex is necessary but not sufficient for visual awareness. Experiments in both patients and normal subjects indicate that parietal and frontal areas make an important contribution to visual awareness, suggesting that reciprocal interactions between dorsal frontoparietal areas and ventral visual cortex may provide a fundamental neural substrate for conscious visual experience.
