© Cambridge University Press 2016. Recent neuroimaging research on disorders of consciousness provides direct evidence of covert consciousness otherwise not detected clinically in a subset of severely brain-injured patients. These findings have motivated strategic development of binary communication paradigms, from which researchers interpret voluntary modulations in brain activity to glean information about patients' residual cognitive functions and emotions. The discovery of such responsiveness raises ethical and legal issues concerning the exercise of autonomy and capacity for decisionmaking on matters such as healthcare, involvement in research, and end of life. These advances have generated demands for access to the technology against …

© Polish Academy of Sciences, Committee for Psychological Sciences 2016. Idiopathic Parkinson's disease (PD) impairs working memory, but the exact nature of this deficit in terms of the underlying cognitive mechanisms is not well understood. In this study patients with mild clinical symptoms of PD were compared with matched healthy control subjects on a computerized battery of tests designed to assess spatial working memory and verbal working memory. In the spatial working memory task, subjects were required to recall a sequence of four locations. The verbal working memory task was methodologically identical except for the modality of the stimuli used, …

© 2016 Gregory et al. Background: Dementia is associated with cognitive and functional deficits, and poses a significant personal, societal, and economic burden. Directing interventions towards older adults with self-reported cognitive complaints may provide the greatest impact on dementia incidence and prevalence. Risk factors for cognitive and functional deficits are multifactorial in nature; many are cardiovascular disease risk factors and are lifestyle-mediated. Evidence suggests that multiple-modality exercise programs can provide cognitive and functional benefits that extend beyond what can be achieved from cognitive, aerobic, or resistance training alone, and preliminary evidence suggests that novel mind-motor interventions (i.e., Square Stepping Exercise; …

Assessing The Feasibility Of Time-Resolved Fnirs To Detect Brain Activity During Motor Imagery, Androu Abdalmalak, Daniel Milej, Mamadou Diop, Lorina Naci, Adrian M. Owen, Keith St Lawrence Jan 2016

Assessing The Feasibility Of Time-Resolved Fnirs To Detect Brain Activity During Motor Imagery, Androu Abdalmalak, Daniel Milej, Mamadou Diop, Lorina Naci, Adrian M. Owen, Keith St Lawrence

BrainsCAN Publications

© 2016 SPIE. Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical technique for detecting brain activity, which has been previously used during motor and motor executive tasks. There is an increasing interest in using fNIRS as a brain computer interface (BCI) for patients who lack the physical, but not the mental, ability to respond to commands. The goal of this study is to assess the feasibility of time-resolved fNIRS to detect brain activity during motor imagery. Stability tests were conducted to ensure the temporal stability of the signal, and motor imagery data were acquired on healthy subjects. The NIRS probes …
