reperception model of hallucinations
   Reperception is also known as downward sensory impulse, top-down signal, re-entrant signal, and feedback signal. The reperception model is an explanatory model of hallucinatory activity which designates hallucinations as reperceptions or re-enactments of previously perceived scenes, objects, or stimuli. It locates the primary source of hallucinatory activity in the limbic system and/or sensory cortical areas. One of the major advantages of present-day reperception models is their ability to account for "compound hallucinations that have the full experiential saturation of sense perceptions. The weaker versions appear to include quasi-realistic, dreamlike phenomena in waking subjects as well. A variant ofthe reperception model, used as an explanatory model for the mediation of "musical hallucinations, is known as the " parasitic memory hypothesis. For a further explanation of the reperception model, see the entry Reperceptive hallucination.
