Segmentation of anatomical regions of brain is that the elementary problem in medical image analysis. The aim of this work is to style an automatic tool for tumor quantification mistreatment imaging image information sets. A tumor segmentation methodology must be developed and validate segmentation on 2nd & 3D imaging information. This methodology doesn't need associate the degree data form...

OBJECTIVES Due to the frequent use of coronary angiography the awareness of Takotsubo stress cardiomyopathy (TSC) has increased although the exact pathophysiology of TSC is still largely unknown. Our objective was to investigate the effects of mental stress on myocardial function, heart rate variability (HRV) and salivary cortisol (SC) in TSC patients. DESIGN This study is a case-control stud...

background: there is a significant proportion of workers with mental disorders who either are struggling at work or who are trying to return to work from a disability leave. objective: using a population-based survey of working adults in ontario, canada, this paper examines the perceptions of workers towards mental disorders in the workplace. methods: data are from a sample of 2219 working adul...

he inclusion of new classifications for such typical childhood behavior as temper tantrums in the upcoming version of the Diagnostic and Statistical Manual of Mental Disorders is lending new urgency to research aimed at finding empirical evidence for psychiatric disorders. The new edition of the manual — known as DSM-5 — due to be published this month, updates the previous 2000 classification o...

There is a long-standing debate about the neurocognitive implementation of mental imagery. One form of mental imagery is the imagery of visual motion, which is of interest due to its naturalistic and dynamic character. However, so far only the mere occurrence rather than the specific content of motion imagery was shown to be detectable. In the current study, the application of multi-voxel patte...

How can functional magnetic resonance imaging (fMRI) advance cognitive theory? Some have argued that fMRI can do little beyond localizing brain regions that carry out certain cognitive functions (and may not even be able to do that). However, in this article, we argue that fMRI can inform theories of cognition by helping to answer at least four distinct kinds of questions. Which mental function...

A common or multiple-demand (MD) pattern of frontal and parietal activity is associated with diverse cognitive demands, and with standard tests of fluid intelligence. In intelligent behaviour, goals are achieved by assembling a series of sub-tasks, creating structured mental programs. Single cell and functional magnetic resonance imaging (fMRI) data indicate a key role for MD cortex in defining...

In the past decade there has been renewed interest in the study of mental imagery. Emboldened by new findings from neuroscience, many people have revived the idea that mental imagery involves a special format of thought, one that is pictorial in nature. But the evidence and the arguments that exposed deep conceptual and empirical problems in the picture theory over the past 300 years have not g...

Mental state reasoning or theory-of-mind has been the subject of a rich body of imaging research. Although such investigations routinely tap a common set of regions, the precise function of each area remains a contentious matter. With the help of functional magnetic resonance imaging (fMRI), we sought to determine which areas are involved when processing mental state or intentional metarepresen...
