Robotic evaluation of sensorimotor and cognitive function following exposure to subconcussive impacts
… 0.50-caliber long-range rifles completed a visually guided reaching (VGR) and reverse visually guided reaching (RVGR) task using Kinarm. Assessments were completed before (n = 18) and after (n = 7) a one-day shooting intervention. While overall performance in snipers did not significantly …

The Role of the Dorsal Premotor and Superior Parietal Cortices in Decoupled Visuomotor Transformations
… controlling the transformations required during visually-guided reaching movements. Our brains are primed to reach directly towards a viewed object, a situation that has been termed a “standard” or coupled reach. Such direct eye-hand coordination is common across species and is crucial for basic …

MURPHY: A neurally-inspired connectionist approach to learning and performance in vision-based robot motion planning
… search with mental images of his arm to solve visually-guided reaching problems in the presence of obstacles whose traditional algorithmic solutions are extremely complex. MURPHY differs from previous approaches to robot motion-planning primarily in his use of an explicit full-visual-field …

Efficacy of using robotics to characterize impaired upper-limb function in a non-human primate model of stroke
… neurobehavioural outcomes were assessed using a visually guided reaching (VGR) and a postural perturbation (PP) KINARM exoskeleton robotic task. Stroke NHP task parameters were compared to control performance (2 healthy, age matched controls) for both the affected and unaffected-arms to determine …

Investigation of Rapid Visual Feedback Processing
The human brain can generate rapid motor responses in less than 100 ms when responding to visual stimuli. The earliest wave of these responses can be time-locked to the stimulus onset (Stimulus-locked Response, SLR) rather than the movement itself. Previous work highlights that these responses are …
