objectives: the role of cognitive process for postural control was shown in dual task studies. however, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. this study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...

Evidence from neuroimaging and cerebellar lesion studies indicate that the cerebellum plays a role in language articulation and verbal fluency. Previous studies have established that distinct areas of the cerebellum are differentially active during each of these tasks, with articulation engaging the anterior cerebellum and verbal fluency activating areas of the right posterolateral cerebellum. ...

Globally, stroke is the second leading cause of death above the age of 60 years, with the actual number of strokes to increase because of the ageing population. Stroke results into chronic conditions, loss of independence, affecting both the families of stroke survivors but also public health systems. Virtual Reality (VR) for rehabilitation is considered a novel and effective low-cost approach ...

Subcortical vascular mild cognitive impairment (svMCI), a prodromal stage of subcortical vascular dementia (SVaD), is primarily associated with frontal injuries, whereas amnestic MCI (aMCI) is associated with temporoparietal injuries. Twenty-seven patients with svMCI, 20 with aMCI, 14 with SVaD, and 10 normal controls underwent motor intentional tasks (force initiation, development, maintenance...

With a long history, dual-task has become one of the most intriguing research fields regarding human brain functioning and cognition. However, findings considering effects of taskinterrelations are limited (especially, in combined motor and cognitive tasks). Therefore, we aimed at developing a measurement system in order to analyse interrelation effects of cognitive and motor tasks. On the one ...

To be effective in many HCI uses, a computational cognitive model must behave like a human, not simply get the job done with the least effort or in the least time. Building computational models that emulate human behavior on complex tasks is an ambitious undertaking, as they must include perception and motor behavior as well as problem-solving, learning and large amounts of knowledge. This proj...

Background: Biological systems exhibit non-linear and spatiotemporal dynamics and structures even at rest. Humans demonstrate a remarkable ability to generate accurate and appropriate motor behaviour under many different and often uncertain environmental conditions. There are many motor movement tasks like eye open and close conditions, hand movements, fist movement etc. Brain controls all moto...

Abstract Background Braking is a critical determinant of safe driving that depends on the integrity cognitive and motor processes. Following stroke, both capabilities are impaired to varying degrees. The current study examines combined impact impairments braking time in chronic stroke. Methods Twenty stroke survivors 20 aged-matched healthy controls performed cognitive, motor, simulator assessm...
