Theory & Psychology, 2007
Top-down processes like heuristics and gap filling create consistency in normal perception. Sometimes top-down processes cause illusory perceptions. Top-down processes are also involved in the creation of hallucinations, experienced in phenomena like sensory deprivation and phantom limbs.

Journal of the American Academy of Child Psychiatry, 1985
This paper reports the results of a retrospective study comparing child psychiatry inpatients, who reported hallucinations, with a control group. The study shows that nonpsychotic children who report hallucinations have significantly more relatives with a history of psychosis, often with an affective component, than controls.

Perceptual and Motor Skills, 1998
Hallucinations, sensory perceptions without environmental stimuli, occur as simple experiences of auditory, gustatory, olfactory, tactile, or visual phenomena as well as mixed or complex experiences of more than one simple phenomenon. The nature of the hallucination assists localization, differential diagnosis, and treatment planning.

The predisposition to hallucinate
Psychological Medicine, 1980SYNOPSISIt is argued that people who are predisposed to mistake a vivid imagination image for a genuine percept (i.e. hallucinators) should show an impaired ability to make clear perceptual–conceptual distinctions (i.e. boundary confusion) and should lack familiarity with internal sources of information.

Current Psychiatry Reports, 2006
Musical hallucinations have been described in numerous neurologic and psychiatric patients, but their pathophysiologic background is not understood. Analyzing the published cases, five subgroups can be separated according to their etiology: hypacusis, psychiatric disorders, focal brain lesions, epilepsy, and intoxication.

The hodology of hallucinations
Cortex, 2008The hodotopic framework is a recent revision of Geschwind's disconnection paradigm incorporating advances in functional and white matter imaging. Its intention is to help clinico-pathological correlations across a range of neurological and psychiatric conditions and generate novel research questions. Here I consider hallucinations within this framework.
