Abstract Motivation: Molecular biotechnology now makes it possible to build elaborate systems models, but the biology community needs information standards if models are be shared, evaluated and developed cooperatively. Results: We summarize Systems Biology Markup Language (SBML) Level 1, a free, open, XML-based format for representing biochemical reaction networks. SBML is software-independent language describing common research in many areas of computational biology, including cell...
Brain-machine interface (BMI) technologies have succeeded in controlling robotic exoskeletons, enabling some paralyzed people to control their own arms and hands. We developed an exoskeleton asynchronously controlled by EEG signals. In this study, enable real-time of the for paresis, we a hybrid system with EMG signals, signals were used estimate its joint angles.Eleven able-bodied subjects two patients upper cervical spinal cord injuries (SCIs) performed hand arm movements, angles...
A brain-machine interface (BMI) is an technology that uses neurophysiological signals from the brain to control external machines. Recent invasive BMI technologies have succeeded in asynchronous of robot arms for a useful series actions, such as reaching and grasping. In this study, we developed non-invasive aiming make movements using subject's own hands by preparing BMI-based occupational therapy assist suit (BOTAS). We prepared pre-recorded actionsa grasping-a-ball movement...
Abstract It is believed that motor performance improves when individuals direct attention to movement outcome (external focus, EF) rather than body itself (internal IF). However, our previous study found an optimal individual attentional strategy depended on imagery ability. We explored whether the ability in stroke patients also affected for control. Individual was determined as either kinesthetic- or visual-dominant by a questionnaire 28 and healthy-controls. Participants then performed...
Abstract Introduction Optimal focus of attention is a crucial factor for improving motor learning. Most previous studies have shown that directing to movement outcome (external focus; EF) more effective than body itself (internal IF). However, our recent demonstrated the optimal attentional strategy in healthy and clinical populations varies depending on individual imagery ability. To explore neurological basis underlying during learning tasks, present study, we measured frontoparietal...
Directing attention to movement outcomes (external focus; EF), not body movements (internal IF), is a better cognitive strategy for motor performance. However, EF effective in some healthy individuals or stroke patients. We aimed identify the neurological basis reflecting individual optimal attentional using functional near-infrared spectroscopy. Sixty-four participants (23 young, 23 elderly, and 18 acute stroke) performed reaching task under IF conditions. Of these, 13 young participants,...
Focus of attention is one the most influential factors facilitating motor performance. Previous evidence supports that external focus (EF) strategy, which directs to movement outcomes, associated with better performance than internal (IF) body movements. However, recent studies have reported EF strategy not effective for some individuals. Furthermore, neuroimaging demonstrated frontal and parietal areas characterize individual optimal attentional strategies tasks. whether sensory cortices...
The Digital Signage Systems using some computer devices are widely used for displaying dynamic information, unlike wall ads that unchanged a certain period. At the replacement time of our university's digital signage system, we need to implement cost effective system. Therefore, developed brand-new style display device low-cost information and open intensive management In this demonstration, introduce total include (1) device, (2) / content
Neurofeedback is a neuromodulation technique used to improve brain function by self-regulating activity. However, the efficacy of neurofeedback training varies widely between individuals, and some participants fail self-regulate To overcome intersubject variation in efficacy, it critical identify factors that influence this type neuromodulation. In study, we considered individual differences cognitive ability may aimed clarify effect working memory (WM) abilities, as characterized sensory...
Biological signals are used to control robotic exoskeletons. Our research group has developed a Brain-Machine Interface (BMI)-based Occupational Therapy Assist Suit (BOTAS), which can be controlled by both electroencephalography (EEG) and electromyography (EMG) signals. This paper presents new method for estimating the joint angles of arms hands BOTAS from EMG using mathematical musculoskeletal models. In six able-bodied participants, succeeded in flexion/extension elbow, wrist,...
Although strong motor coordination in intrinsic muscle coordinates has frequently been reported for bimanual movements, extrinsic visual is also crucial various tasks. To explore the mechanisms terms of frame reference, here we characterized implicit bilateral interactions visuomotor Visual perturbations (finger-cursor gain change) were applied while participants performed a rhythmic tracking task with both index fingers under an in-phase or anti-phase relationship coordinates. When they...
In Tokyo University of Agriculture and Technology, by the part information strategy, we promote to abolish conventional computer room, make user bring user's own (BYOD: Bring Your Own Device). The trend this BYOD is expanding progressively in other universities Japan. type device wide variety, its usability, too. situation, it increases cost teacher due difference operation.
The long-term effects of impairment have a negative impact on the quality life stroke patients in terms not using affected limb even after some recovery (i.e., learned non-use). Immersive virtual reality (IVR) has been introduced as new approach for treatment rehabilitation. We propose an IVR-based therapeutic to incorporate positive reinforcement components motor coordination opposed constraint-induced movement therapy (CIMT). This study aimed investigate effect IVR-reinforced physical that...
Introduction: Parkinson’s disease is a progressive neurological disorder characterized by the preferential loss of dopaminergic neurons in substantia nigra, which project to striatum. The prominent motor symptoms, are its cardinal features. Consequently, has been primarily considered movement. However, increasing evidence indicated that affects not only domain but also cognitive domain. Increasing indicates patients with have an impaired ability recognize emotional facial expressions. Recent...
Difficulties with visual perspective-taking among individuals autism spectrum disorders remain poorly understood. Many studies have presumed that first-person input can be mentally transformed to a third-person perspective during tasks; however, existing research has not fully revealed the computational strategy used by those for taking another person's perspective. In this study, we designed novel approach test using opposite-directional effect children disorders. This refers how as alters...

Approximately 80 percent factors of traffic accident is human error when we check report for last 5 years. Due to shortage domestic vessel crew cost cutting, number has been decreasing rate increasing. In order lighten work load crew, designed supports watching from a distant place. Because taking high cost, streaming between ship land difficult. this paper, achieved low...
Abstract The ability to understand the way other people see world differs from one's own viewpoint is referred as ‘‘visual perspective‐taking’’ (VPT). Previous studies have demonstrated behavioral performance in level 2 VPT (VPT2), that two different observers can unique visual experiences of same scene or object depending on observers’ physical location, changes during childhood. However, developmental aspects underlying neural mechanisms VPT2 remains unknown. We measured hemodynamic...
