Human beings are able to rapidly detect the presence of object categories such as animals or vehicles, even when a scene is presented very briefly. The use of functional magnetic resonance imaging during an object categorization task now indicates that the rapid detection of categorical information in natural scenes is mediated by a category-specific biasing mechanism in object-selective cortex that operates across the visual field.
