The pathophysiology of visual hallucinations in Parkinson's disease has yet to be characterized. Although stimulus-driven ("bottom-up") processes are known to be impaired, the role of "top-down" processes remains to be determined. Distinguishing between conscious and non-conscious detections (i.e. access to consciousness) may be a valuable way of monitoring top-down processes. Conscious access ...

Visual perceptual disturbances in psychiatry range from absence of sensory stimuli to sensory distortion or deception [1]. Although less common than auditory hallucination, the presence of visual perceptual disturbance in patients with mental illness can be distressing [2]. Ascertaining the cause and type of visual perceptual disturbance occurring in symptomatic patients can be difficult to del...

background: ketamine increases blood pressure and heart rate. propofol is an anesthetic drug with rapid recovery, but it causes respiratory depression, low heart rate and low blood pressure. combination of ketamine and propofol provides sedation, analgesia, and rapid recovery with hemodynamic stability and minimal respiratory depression. there have been a few studies about the effect of differe...

In Phase I of the investigation, 70 5s were assigned to one of three treatment conditions: hypnotic induction, instructions to simulate hypnosis, or imagination control. All 5s were assessed on Orne's two indexes of trance logic (the transparent hallucination and the double hallucination). The imagination controls consistently showed trance logic as often as the hypnotic Ss. Depending upon the ...

A novel face hallucination method is proposed in this paper for the reconstruction of a high-resolution face image from a low-resolution observation based on a set of highand low-resolution training image pairs. Different from most of the established methods based on probabilistic or manifold learning models, the proposed method hallucinates the high-resolution image patch using the same positi...

Abstract Disjunctivists maintain that perceptual experiences and hallucinatory are distinct kinds of event with different metaphysical natures. Moreover, given their view about the nature cases, disjunctivists must deny kind experience can occur during hallucination. However, it is widely held grant converse claim, to effect occurs even perception. This paper challenges thought. As we will see,...

Obtaining a high-quality frontal face image from low-resolution (LR) non-frontal is primarily important for many facial analysis applications. However, mainstreams either focus on super-resolving near-frontal LR faces or frontalizing high-resolution (HR) faces. It desirable to perform both tasks seamlessly daily-life unconstrained images. In this paper, we present novel Vivid Face Hallucination...

Identifying an individual from surveillance video is a difficult, time consuming and labour intensive process. The proposed system aims to streamline this process by filtering out unwanted scenes and enhancing an individual’s face through super-resolution. An automatic face recognition system is then used to identify the subject or present the human operator with likely matches from a database....

Face hallucination method is proposed to generate highresolution images from low-resolution ones for better visualization. However, conventional hallucination methods are often designed for controlled settings and cannot handle varying conditions of pose, resolution degree, and blur. In this paper, we present a new method of face hallucination, which can consistently improve the resolution of f...

The objectives of the present study were to examine the degree of co-existence of hallucinations and delusions in the nonclinical population. In addition, we wished to investigate the role of metacognitions in hallucinations and delusions. Finally, we explored the relative roles of positive and negative metacognitive beliefs in proneness to hallucinations and delusions. Three hundred and thirty...
