Perceptual asymmetry in texture perception.
A fundamental property of human visual perception is our ability to distinguish between textures. A concerted effort has been made to account for texture segregation in terms of linear spatial filter models and their nonlinear extensions. However, for certain texture pairs the ease of discrimination changes when the role of figure and ground are reversed. This asymmetry poses a problem for both...
متن کاملCerebral Asymmetry in Insomnia Sufferers
Cerebral asymmetry is used to describe the differences in electroencephalographic activity between regions of the brain. The objective of this study was to document frontal, central, and parietal asymmetry in psychophysiological (Psy-I) and paradoxical (Para-I) insomnia sufferers as well as good sleeper (GS) controls, and to compare their patterns of asymmetry to others already found in anxiety...
متن کاملBlack-white asymmetry in visual perception.
With eleven different types of stimuli that exercise a wide gamut of spatial and temporal visual processes, negative perturbations from mean luminance are found to be typically 25% more effective visually than positive perturbations of the same magnitude (range 8-67%). In Experiment 12, the magnitude of the black-white asymmetry is shown to be a saturating function of stimulus contrast. Experim...
متن کاملAsymmetry Analysis in Rodent Cerebral Ischemia Models1
Materials and Methods. Segmentation of ischemic stroke was performed on magnetic resonance (MR) images of sub acute rodent cerebral ischemia. Eight adult male Wistar rats weighing 225–300 g were anesthetized with halothane mix of 70% nitrous oxide/30% oxygen. Animal core temperature was maintained at 37°C during the entire surgical dure, including occlusion of the middle cerebral artery (MCA) a...
متن کاملCerebellar Asymmetry and Its Relation to Cerebral Asymmetry
26 27 Asymmetry of the human cerebellum was investigated using intrinsic functional 28 connectivity. Regions of functional asymmetry within the cerebellum were identified 29 during resting-state functional MRI (fMRI; N=500) and replicated in an independent 30 cohort (N=500). The most strongly right lateralized cerebellar regions fell within the 31 posterior lobe including Crus I and Crus II in ...
