OBJECTIVE The recent nonlinear analyses of electroencephalogram (EEG) data have shown that the correlation dimension (D2) reflects the degree of integration of information processing in the brain. There is now considerable evidence that auditory hallucination (AH) reflects dysfunctional gamma and beta frequency oscillations. Gamma oscillations are thought to reflect internally driven representa...

Face hallucination is to reconstruct a high-resolution face image from a low-resolution one based on a set of highand low-resolution training image pairs. This paper proposes an example-based two-step face hallucination method through coefficient learning. Firstly, the low-resolution input image and the low-resolution training images are interpolated to the same high-resolution space. Minimizin...

In this paper, we propose a face hallucination method using eigentransformation with distortion reduction. Different from most of the proposed methods based on probabilistic models, this method views hallucination as a transformation between different image styles. We use Principal Component Analysis (PCA) to fit the input face image as a linear combination of the lowresolution face images in t...

The aim of the current study was to examine how belief in the validity of hallucinations relates to the association between hallucination frequency and associated distress. In a sample of inpatients with psychotic symptoms, results demonstrated that hallucination believability predicted later distress after controlling for symptom frequency. In addition, results were consistent with the hypothe...

Introduction: Acute and Transient Psychotic disorder (ATPD) is defined by the ICD-10 as hallucinations, delusions, and/or senseless or nonsensical speech having an acute [1]. The distinguishing characteristic of ATPD its abrupt onset. Second, there are symptoms present, third, related stress [2].
 Clinical Findings: Sleep disturbance, aggressiveness, muttering to self, irritability, irrele...

BACKGROUND The exact cerebral structural and functional mechanisms under the auditory verbal hallucinations (AVHs) in schizophrenia are still unclear. The Deutsch "high-low" word illusion might trigger attentional responses mimicking those under AVHs. METHODS We therefore have invited 16 patients with first-episode, paranoid schizophrenia, and 16 age- and gender-matched healthy volunteers to ...

BACKGROUND Dysconnectivity hypothesis of schizophrenia has been increasingly emphasized. Recent researches showed that this dysconnectivity might be related to occurrence of auditory hallucination (AH). However, there is still no consistent conclusion. This study aimed to explore intrinsic dysconnectivity pattern of whole-brain functional networks at voxel level in schizophrenic with AH. METH...

The great majority of studies on repetitive transcranial magnetic stimulation (rTMS) as a therapeutic tool for auditory verbal hallucinations (AVH) have used 1-Hz stimulation with inconsistent results. Recently, it has been suggested that 20-Hz rTMS has strong therapeutic effects. It is conceivable that this 20-Hz stimulation is more effective than 1-Hz stimulation. The aim of this preliminary ...

OBJECTIVE Large epidemiological surveys conducted in the developed world have found rates of psychotic symptoms in the general population to be as high as 10-28%. However, there are few data available from developing countries, including African countries, on the prevalence and correlates of psychotic symptoms. This study investigates the prevalence and correlates of psychotic symptoms (ie hall...
