The purpose of this study was to investigate whether artificial neural networks (ANN) are able to decode participants' conscious experience perception from brain activity alone, using complex and ecological stimuli. To reach the aim we conducted pattern recognition data analysis on fMRI data acquired during the execution of a binocular visual rivalry paradigm (BR). Twelve healthy participants w...

Common wisdom and scientific evidence suggest that good decisions require conscious deliberation. But growing evidence demonstrates that not only conscious but also unconscious thoughts influence decision-making. Here, we hypothesize that both consciously and unconsciously acquired memories guide decisions. Our experiment measured the influence of subliminally and supraliminally presented infor...

Cognitive models of attention propose that visual perception is a product of two stages of visual processing: early operations permit rapid initial categorization of the visual world, while later attention-demanding capacity-limited stages are necessary for the conscious report of the stimuli. Here we used the attentional blink paradigm and fMRI to neurally distinguish these two stages of visio...

The higher the number of clock cycles per main memory access becomes,the more important it will be to use caches to their full potential. We present amethod for finding good points at which to insert prefetch instructions to alreadycache-consciously allocated data.

Abstract The structure and methods of separating the space in consciously formed objects are a reflection philosophical theories historical processes, specific emanation ocentricism, anthropocentrism anti-centrism. Constructing an architectural object, i.e., for it within it, is determined by types activities, methods, purpose.

BACKGROUND Dissociative reactions in post-traumatic stress disorder (PTSD) have been regarded as strategic responses that limit arousal. Neuroimaging studies suggest distinct prefrontal responses in individuals displaying dissociative and hyperarousal responses to threat in PTSD. Increased prefrontal activity may reflect enhanced regulation of limbic arousal networks in dissociation. If dissoci...

The implications of priming experiments for a structural theory of the mental lexicon depend critically on the development of an adequate theory of the mechanics of priming. Masked priming techniques may simplify this task, since consciously perceived relationships play no role in masked priming. The implications of adopting an activation-based approach to morphological priming is discussed, an...

Grapheme-color synesthetes experience colors when they see printed letters of the alphabet. Currently, we tested four "projector" synesthetes, whose colors evoked by graphemes have sensory support or quale and appear to be restricted spatially to the letters like real colors. We use three different kinds of puzzle pictures that contained hidden letters, which require 30 s or more for nonsynesth...

According to recent evidence, stimulus-tuned neurons in the cerebral cortex exhibit reduced variability in firing rate across trials, after the onset of a stimulus. However, in order for a reduction in variability to be directly relevant to perception and behavior, it must be realized within trial--the pattern of activity must be relatively stable. Stability is characteristic of decision states...
