This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Near-infrared spectroscopy (NIRS) has been gaining increasing attention as a brain-computer interface (BCI) modality. However, communication rates offered by this technology are not yet practical for clinical implementation. This thesis investigates the feasibility of enhancing the speed and accuracy attainable by NIRS-BCIs. To date, most studies have utilized activity from a single cortical region, particularly the anterior prefrontal cortex (aPFC), to discern two non-motor-based mental states. However, cognitive processes require coordination between several, spatially-distributed areas. Additional cortical information may help improve classification of mental states, particularly combinations of more than two. Furthermore, testing has largely focused on offline analyses, despite the possibility of enhanced cortical control attainable with feedback. Lastly, NIRS-BCI work has primarily involved able-bodied participants, most of which were offline. In an initial offline study, we investigated the value of utilizing cortical activity measured from multiple brain regions to differentiate all possible combinations of two cognitive tasks and rest. With prefrontal and parietal measurements, average binary and ternary accuracies exceeded 80% and 70%, respectively. Accuracies and information transfer rates (ITRs) improved significantly with the inclusion of measurements beyond the aPFC. A second study was conducted to evaluate ternary classification accuracies achievable in an online system that offered classification feedback. An average online accuracy of 74.2 Âą 14.8% was attained, representing further improvements in NIRS-BCI speed and accuracy. In a final study, we tested an online system developed for a candidate BCI user with severe, congenital muscular impairments. The binary system made use of prefrontal measurements beyond the aPFC and was tailored for the user prior to each online session. Offline and online accuracies of 66.9 Âą 9.11% and 63.33%, respectively, were achieved. Collectively, these findings demonstrate the value of considering multiple brain regions and offering online classification feedback to realize a faster and more accurate NIRS-BCI.

Available in PDF, EPUB and Kindle. Book excerpt: Most people find colorful brain scans highly compelling—and yet, many experts don’t. This discrepancy begs the question: What can we learn from neuroimaging? Is brain information useful in fields such as psychiatry, law, or education? How do neuroscientists create brain activation maps and why do we admire them? Casting Light on The Dark Side of Brain Imaging tackles these questions through a critical and constructive lens—separating fruitful science from misleading neuro-babble. In a breezy writing style accessible to a wide readership, experts from across the brain sciences offer their uncensored thoughts to help advance brain research and debunk the craze for reductionist, headline-grabbing neuroscience. This collection of short, enlightening essays is suitable for anyone interested in brain science, from students to professionals. Together, we take a hard look at the science behind brain imaging and outline why this technique remains promising despite its seldom-discussed shortcomings. Challenges the tendency toward neuro-reductionism Deconstructs hype through a critical yet constructive lens Unveils the nature of brain imaging data Explores emerging brain technologies and future directions Features a non-technical and accessible writing style

Available in PDF, EPUB and Kindle. Book excerpt: A brain-computer interface (BCI) allows individuals to communicate through the modulation of regional brain activity. Clinical near-infrared spectroscopy (NIRS) is used to monitor changes in cerebral blood oxygenation due to functional activation. It was hypothesized that visually-cued emotional induction tasks can elicit detectable activity in the prefrontal cortex. Data were collected from eleven participants as they performed positively and negatively-valenced emotional induction tasks. Baseline and activation trials were classified offline with accuracies from 75.0--96.7% after applying a feature selection algorithm to determine optimal performance parameters for each participant. Feature selection identified common discriminatory features across participants and relationships between performance parameters. Additionally, classification accuracy was used to quantify NIRS hemodynamic response latency. Significant increases in classification rates were found as early as 2.5 s after initial stimulus presentation. These results suggest the potential application of emotional induction as a NIRS-BCI control paradigm.

Book excerpt: In the last 15 years, a recognizable surge in the field of Brain Computer Interface (BCI) research and development has emerged. This emergence has sprung from a variety of factors. For one, inexpensive computer hardware and software is now available and can support the complex high-speed analyses of brain activity that is essential is BCI. Another factor is the greater understanding of the central nervous system including the abundance of new information on the nature and functional correlates of brain signals and improved methods for recording these signals in both the short-term and long-term. And the third, and perhaps most significant factor, is the new recognition of the needs and abilities of people disabled by disorders such as cerebral palsy, spinal cord injury, stroke, amyotrophic lateral sclerosis (ALS), multiple sclerosis, and muscular dystrophies. The severely disabled are now able to live for many years and even those with severely limited voluntary muscle control can now be given the most basic means of communication and control because of the recent advances in the technology, research, and applications of BCI. This book is intended to provide an introduction to and summary of essentially all major aspects of BCI research and development. Its goal is to be a comprehensive, balanced, and coordinated presentation of the field's key principles, current practice, and future prospects.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain-computer interfaces (BCI) are being investigated as an access pathway to communication for individuals with physical disabilities as they bypass the need for voluntary motor control to operate. However, to date, minimal research has investigated the use of BCIs for children. This thesis describes the development of a paediatric brain-computer interface to identify positive and negative emotional states from changes in hemodynamic activity of the pre-frontal cortex. To train and test the BCI, 10 typically developing children aged 8-14 underwent a session of emotion induction trials while their hemodynamic activity was measured with near-infrared spectroscopy (NIRS). BCI performance was evaluated both offline, using cross-validation, and online, using real-time prediction results. Offline differentiation rates were comparable to studies with adult populations, and online prediction was feasible, yet failed to surpass the 70% accuracy threshold of 'effective' BCI use. Interparticipant and intersession variability in BCI performance was also investigated.
