Objective: The relationship between dreams and schizophrenia has been a subject of discussion for many years ago. Little is known about details of dream contents in schizophrenia. The aim of this study was to assess the relationship between dream contents and positive and negative symptoms in schizophrenia.
Methods: Fifty schizophrenic patients in Beheshti Hospital, Kerman, Iran, over a 6-month period from July to December 2002, were evaluated for dream contents using free recall of dreams and a checklist which was provided in a previous pilot study. Positive and negative symptoms were evaluated by the Positive and Negative Syndrome Scale (PANSS). Data were analyzed by the Statistical Package for Social Sciences, version 9 software.
Results: Forty-five (90%) patients reported at least one recurrent dream in the previous 6 months prior to psychiatric hospital admission. The most frequent dream was a familiar person (82%). Dreams which contained homosexuality and dreams in color were related only to a negative scale (f=4.1, p<0.05, f=4.6, p<0.05) and dreams which contained wild animals were related to a positive scale (f=4.4, p<0.05). Some other dream contents were related to both positive and negative symptoms and some were related to no scores of PANSS.
Conclusion: Positive and negative scales as 2 separate dimensions may have specific related symptoms. Each dimension of schizophrenia (positive/negative) could have their own specific dream contents. Future studies may clarify many other aspects of dream contents in schizophrenia.

Increasing the flame retardancy of lignocellulosic materials such as × can effectively enable their wide use. This study examines the fireproofing process of Miscanthus particles using an eco-friendly process by grafting phytic acid and urea in aqueous solution. Miscanthus particles underwent a steam explosion step before being grafted.

Objectives: Research supports cognitive behavioral therapies for nightmares (CBT-N) in adults. However, the nuances of implementation and unstandardized nomenclature for treatment components has created confusion in the field. To provide clarification, an expert consensus panel convened to review treatment manual components and to develop guidelines for the standardized implementation and terminology of CBT-N.

A central tenet of Freudian dream theory holds that there is thematic coherence within all dreams, even those containing scene and plot discontinuities. While other models support varying degrees of dream coherence, none address the question of how, or even whether, coherence can be identified in dreams with such discontinuities. Here, we objectively test the ability of judges to evaluate the coherence of individual dream narratives.

Introduction: While the fact that visual stimuli synthesized by Artificial Neural Networks (ANN) may evoke emotional reactions is documented, the precise mechanisms that connect the strength and type of such reactions with the ways of how ANNs are used to synthesize visual stimuli are yet to be discovered. Understanding these mechanisms allows for designing methods that synthesize images attenuating or enhancing selected emotional states, which may provide unobtrusive and widely-applicable treatment of mental dysfunctions and disorders.
Methods: The Convolutional Neural Network (CNN), a type of ANN used in computer vision tasks which models the ways humans solve visual tasks, was applied to synthesize ("dream" or "hallucinate") images with no semantic content to maximize activations of neurons in precisely-selected layers in the CNN.
