New methods of measurement and imaging have enabled the objective measurement of phenomena of consciousness. These methods have yielded surprising results indicating that patients may be conscious despite fulfilling the typical criteria of unconsciousness, such as unresponsiveness to environmental stimuli. The assessments of the contents of consciousness have especially elucidated the localization and time of generation of a conscious visual sensation. It has recently been suggested that it might even be possible to "read" the contents of consciousness directly from the brain by using cerebral imaging.
