The cognitive abilities are functions in human brain. They are closely with the real life. The cognitive abilities are likely to be decreased when human gets older and older. Fortunately, due to the plasticity of human brain, it is possible to help recover and rehabilitate brain function. Those efforts are called brain training and cognitive ability training. The cognitive ability training needs continuous trials and efforts. But many users feel boring because of simple repetitive works. This paper proposes a cognitive training system implemented in a smart device. The proposed system is designed to make users to focus on the repetitive training by using game-based tasks on the smart device. It shows that the proposed system is effective to attention and flexible on cognitive training game.

The purpose of this review was to investigate feasibility of intensive virtual reality training to improve upper extremity function with brain plasticity of individuals with stroke through the literature. The recovery of the paretic upper extremity depends on regularity and intensity of training as use-dependent plasticity. In resent, virtual reality program has been widely used in the occupational therapy field of augmented stroke rehabilitation. There is a growing body of evidence that virtual reality training of the paretic extremity induces brain plasticity associated with motor improvement. In terms of therapeutic feasibility to improve paretic upper extremity, recent research has explored several important factors of virtual reality training for recovery of upper extremity motor function. These factors include high repetition intensity, high motivation like type of game, enhanced multisensory feedback regarding performance, and interactive task-oriented training. Therefore, occupational therapy combined with intensive and repetitive virtual reality training will enhance recovery of upper extremity motor function after stroke.

As the proportion of old people in contemporary societies steadily increases, the influence on cognitive rehabilitation strategy of the memory deficit associated with normal and pathological aging grows greater as well. This paper reviewed the current memory rehabilitation techniques for older adults. In the first part of this article, human memory systems as a framework for understanding memory aging were considered. In the second part, research findings concerning memory performance in normal aging and Alzheimer's disease were reviewed. Finally, recent evidence for the kinds of memory rehabilitation procedures with proven efficacy were offered. The existent memory rehabilitation technique have focused on prompt of residual explicit memory, use of preserved implicit memory, utilization of memory external memory aids. A suggestion of memory training based on brain plasticity as a novel approach is offered.

Mathematical ability is important for academic achievement and technological renovations in the STEM disciplines. This study concentrated on the relationship between neural basis of mathematical cognition and its mechanisms. These cognitive functions include domain specific abilities such as numerical skills and visuospatial abilities, as well as domain general abilities which include language, long term memory, and working memory capacity. Individuals can perform higher cognitive functions such as abstract thinking and reasoning based on these basic cognitive functions. The next topic covered in this study is about individual differences in mathematical abilities. Neural efficiency theory was incorporated in this study to view mathematical talent. According to the theory, a person with mathematical talent uses his or her brain more efficiently than the effortful endeavour of the average human being. Mathematically gifted students show different brain activities when compared to average students. Interhemispheric and intrahemispheric connectivities are enhanced in those students, particularly in the right brain along fronto-parietal longitudinal fasciculus. The third topic deals with growth and development in mathematical capacity. As individuals mature, practice mathematical skills, and gain knowledge, such changes are reflected in cortical activation, which include changes in the activation level, redistribution, and reorganization in the supporting cortex. Among these, reorganization can be related to neural plasticity. Neural plasticity was observed in professional mathematicians and children with mathematical learning disabilities. Last topic is about mathematical creativity viewed from Neural Darwinism. When the brain is faced with a novel problem, it needs to collect all of the necessary concepts(knowledge) from long term memory, make multitudes of connections, and test which ones have the highest probability in helping solve the unusual problem. Having followed the above brain modifying steps, once the brain finally finds the correct response to the novel problem, the final response comes as a form of inspiration. For a novice, the first step of acquisition of knowledge structure is the most important. However, as expertise increases, the latter two stages of making connections and selection become more important.
