Objectives: We have examined the specificity of face recognition networks in relation to other object recognition modules in normal subjects. In particular, we addressed a current challenge in cognitive neuroscience by using a novel paradigm that allowed for an explicit separation of the neural correlates of the sensory, perceptual and motor components in holistic perceptual decision. This strategy, which was anchored on a well defined neurochronometry of cognitive processes helped elucidate the contribution of different regions in the visual stream and insular networks in perceptual decision making. The emergence of holistic percepts occurred in the absence of change in local saliency cues. This allowed for assessing mechanisms of global perceptual awareness irrespective of changes in local sensory evidence.
