schizophrenia and various neurological disorders have some signs and symptoms. visual hallucinations are one of such disorders. the related studies in some diseases for example parkinson disease and lewy body dementia indicate that acetylcholine (ach) plays a significant role in neuropsychiatric manifestation and its association with visual hallucination; therefore, visual hallucinations occur ...

background: parkinson's disease (pd) is a neurodegenerative disorder impairing motor, verbal and other abilities. visual evoked potential (vep) assessment is a useful method for analysis of visual system and its function. the present study was designed in order to evaluate whether vep changes are associated with pd. m aterials and methods: in the present study, 100 subjects encompassing 40 pati...

Objective: Isolated visual hallucinations is considered as the Charles Bonnet syndrome. Ophtalmic or brain organic disease is a necessary or exclusionary criterion for diagnosis. In previous reports, it reported only solitary hallucination. In this report, we found multiple hallucinations. Case Presentation: In this article we report a 64 year-old blind man with renal failure under hemodialy...

College students screened for hallucination-proneness using the Launay-Slade Hallucination Scale (LSHS) were compared on measures of self-report vividness of imagery and on behavioral measures of imagery and perception (visual and auditory). Specifically, we tested the hypothesis whether hallucination-prone individuals would show smaller differences between imagery and perception performance, w...

It is generally recognized that learning is a useful tool for solving vision problems. However, at present time, neither learning nor vision is a well understood problem. It is even less clear how one might be able to put the two together. In this paper I will attempt to study one small aspect of this problem of using learning in vision. In particular I will study how learning might be used for...
