Several groups have reported that visual imagery activates the same cortical regions as those involved in visual perception. Visual imagery and visual perception might have common neural substrates in healthy people as well as in people with visual hallucinations. More particularly, failure to discriminate between imagined and perceived pictures might be involved in visual hallucinations. Reality-monitoring failure appears to be involved in hallucinations and can occur in any modality. Visual mental imagery might be critical in this distinction. ![]() Such distinction can normally be achieved by assessing the context of the information: perceived information contains more sensory details, while imagined information has details about the cognitive operations executed during its formation. One type of source-monitoring process, referred to as ‘reality-monitoring’, ensures that the memories for perceived events are distinguished from those for imagined events. Source monitoring refers to the ability to remember the origin of information.
