Visual perception and visual mental imagery, the faculty whereby we can revisualise a visual item from memory, have often been regarded as cognitive functions subserved by common mechanisms. Thus, the leading cognitive model of visual mental imagery holds that visual perception and visual imagery share a number of mental operations, and rely upon common neural structures, including early visual...

Visual imagery is the invention or recreation of a perceptual experience in the absence of retinal input.The degree to which the same neural representations are involved in both visual imagery and visual perception is unclear. Previous studies have shown that visual imagery interferes with perception (Perky effect). We report here psychophysical data showing a direct facilitatory effect of visu...

Complex pictorial information can be represented and retrieved from memory as mental visual images. Functional brain imaging studies have shown that visual perception and visual imagery share common neural substrates. The type of memory (short- or long-term) that mediates the generation of mental images, however, has not been addressed previously. The purpose of this study was to investigate th...

Vivid emotional mental imagery has been identified across a range of mental disorders. In bipolar spectrum disorders - psychopathologies characterized by mood swings that alternate between depression and mania, and include irritability and mixed affect states - mental imagery has been proposed to drive instability in both 'positive' and 'negative' mood. That is, mental imagery can act as an "em...

Digital cinema (d-cinema) is the highest quality electronic motion imagery for entertainment. The cinema is presented in a theatrical environment, with high brightness projectors, high rate data transfer, and high resolution color imagery. The entertainment industry uses formats that are specific to film-based electronic imagery. This report describes software tools for viewing digital cinema s...

based on some important factors such as abstraction of imagination and also the power of soul on creation external imagery, molla sadra utters his claim about bodily resurrection and creation of eternal body by soul. and also he clarifies the way of creation and its quality. examining and understanding the dominant system on the world and resurrection, leads us to this point that in the world c...

BACKGROUND Motor imagery is considered as a promising therapeutic tool for rehabilitation of motor planning problems in patients with cerebral palsy. However motor planning problems may lead to poor motor imagery ability. AIM The aim of this functional magnetic resonance imaging study was to examine and compare brain activation following motor imagery tasks in patients with hemiplegic cerebra...
