A sizable fraction of current research into human visuospatial knowledge processing explicitly or implicitly suggests a spatial processing of certain knowledge types and a visual processing of others. Similarly, many formal and technical approaches for representing and processing visuospatial information in artificial intelligence, in computational cognitive modeling, or in knowledge representa...

The association of sodium valproate with cognitive functions was studied in 29 patients with complex absence seizures. Seventeen patients were on monotherapy and twelve on polypharmacy with sodium valproate. Cognitive functions assessed were attention, speech, visuo-speciat perception, memory and intelligence. Behavioral disturbances were also assessed. Two assessments were made six months apar...

Prevalence of hyperactive syndrome in 2160 primary school children between the age of 6-12 years was found to be 4.67%. The ratio of male, female distribution of hyperactive syndrome was found to be 4.74: 1. It was significantly associated with type of school (only in girls), age (only in boys) and occupation of father (only in boys). Hyperkinetic behaviour of children was not significantly ass...

Specialized, bimodal neural systems integrate visual and tactile information in the space near the hand. Here, we show that visuo-tactile representations allow attention to influence early perceptual processing, namely, figure-ground assignment. Regions that were reached toward were more likely than other regions to be assigned as foreground figures, and hand position competed with image-based ...

A 72-year-old man with pure topographical disorientation following a focal hemorrhage in the right forceps major of splenium was assessed at 2 weeks and 3 months after the onset. Initially, he could identify familiar buildings and landmarks, but noted topographical disorientation, dysfunction in sense of quarters, and in visuo-spatial function. The improvement of topographical disorientation wa...

Abacus experts exhibit superior short-term memory for digits, but the underlying neurophysiological mechanism remains unknown. Using event-related fMRI, we examined the brain activity of abacus experts and non-experts during the memory retention period of a delayed match-to-sample task using digits as stimuli. In controls, activity was greater in cortical areas related to verbal working memory,...

As we are encountering to the aging society, the interest of serious games gets increasing. In this respect,‘SqueeView’ is aimed at enhancing visuo-spatial cognition of the elderly. In an empirical study with 35 mature adults, it was revealed that SqueeView had a significant effect for improving their visuo-spatial cognition capability. However, the SqueeView game that is based on the desktop c...
