We systematically reviewed the localization of focal brain lesions that cause isolated hallucination in a single sensory modality. Case reports of post-lesion nonparoxysmal hallucination in 1 (and only 1) of 3 sensory modalities (i.e., visual, auditory, somatic) were reviewed, and the content of the qualitative descriptions was analyzed for each modality. The lesion is practically always locate...

Neuronal underpinnings of auditory verbal hallucination remain poorly understood. One suggested mechanism is brain activation that is similar to verbal imagery but occurs without the proper activation of the neuronal systems that are required to tag the origins of verbal imagery in one's mind. Such neuronal systems involve the supplementary motor area. The supplementary motor area has been asso...

Face Hallucination is a super-resolution technique to obtain high-resolution facial images by taking low-resolution facial images as input. In this paper problem of face hallucination has been approached by using sparse Representation. The image has to be subdivided into different segments so that image pixel information can be retrieved easily from each segment. Each small patch of the image h...

Auditory hallucination is a positive symptom of schizophrenia and has significant impacts on the lives of individuals. People with auditory hallucination require considerable assistance from mental health professionals. Apart from medications, they may apply different lay methods to cope with their voice hearing. Results from qualitative interviews showed that people with schizophrenia in the C...

Levetiracetam, a relatively new antiepileptic drug (AED), is used mainly as adjuvant and less as monotherapy of seizure. Though rare, Levetiracetam is reported to induce hallucination. To highlight the potential of this adverse drug event, we report a seizure-case that had auditory hallucination with Levetiracetam. A 32-year lady had 7-year history of unresponsive spells which increased in the ...

Musical hallucination is a type of complex auditory hallucination. Possible etiologies are deafness, psychiatric disorders such as schizophrenia, major depression, use of medication and stress, besides neurologic diseases including epilepsy, stroke and cancer. Uncommon etiologies encompass infectious diseases, metabolic disorders, and sensory deprivation. Although musical hallucinations have a ...

Deep models have achieved impressive performance for face hallucination tasks. However, we observe that directly feeding the hallucinated facial images into recognition models can even degrade the recognition performance despite the much better visualization quality. In this paper, we address this problem by jointly learning a deep model for two tasks, i.e. face hallucination and recognition. I...

-------------------------------------------------------ABSTRACT--------------------------------------------------To Study about the Face Hallucination technique and to create high-resolution face images. After that Apply Artificial intelligence based cuckoo search technique to get high hallucination parameters. Cuckoo work on the colored image and performing face hallucination. PSNR, EPI, MOS, ...

Previous research suggests that measures of dysphoria relate to positive schizophrenic symptoms. These relationships have rarely been studied within the dimensionality of psychopathology framework. The present study examined the relationship between 3 distinct aspects of dysphoria (depression and state and trait anxiety) and delusion and hallucination proneness in a nonclinical sample of young ...

INTRODUCTION Auditory hallucinations occur in schizophrenia and also in the general population. However, evidence points to differences in the nature and the mechanisms of clinical and non-clinical hallucinations, challenging the dominant assumption that they represent the same phenomenon. The current study extended this evidence by examining voice identity perception in hallucination-prone ind...
